VirtualBox.exe fails to run

[yefkov]

VirtualBox.exe failed with the message:
Callee RC: E_NOINTERFACE (0x80004002)

VBoxSVC.log reports:

Running as administrator -> no error

Previous version (4.2.16) does not have this issue.

[Frank Mehnert]

Duplicate of #12079.

[yefkov]

It is not an installer issue.

[Frank Mehnert]

I did not say so. The binary on some mirrors seems to be incorrect. It needs time to resynchronize after I removed + re-uploaded the binary.

[yefkov]

The md5 and sha256 sums of the installer I've downloaded match the sums published on the web site. Are you still insisting that the problem in the binary?

[Frank Mehnert]

What is the size of your Windows package?

[Frank Mehnert]

Could you also uninstall VBox and then re-install VBox 4.2.18? Does it make any difference?

[Frank Mehnert]

To be more clear, now I also assume that your problem is not caused by a partial download of the Windows package but still, what happens if you completely uninstall VBox and then re-install VBox 4.2.18?

[yefkov]

I tried several times. No difference.

Additional info:
My colleague has Windows 7 64bit as host OS. He can not reproduce the issue. My configuration is Windows 7 32bit.

Could you try if ​this build fixes the problem for you?

Which Windows 7 version is that exactly, I assume Windows 7 Professional 32-bit?

[Frank Mehnert]

Guys, we need some help here in finding the problem. We are not able to reproduce the problem. We installed Windows 7 / professional 32-bit locally and installed VBox 4.2.18 there. No problem starting the GUI and starting a VM at all. So what's different to your configuration?

[Pedro Serrano]

Similar issue. Vboxsvc.exe service fails to start and "headless" VMs refuse to start. VMs do start while Virtualbox console is open but they crash when Virtualbox console is closed (the whole story is, if you close the console while a VM is running, vboxsvc service stops and the VM crashes).

I don't know what is the difference. May be third party software, antivirus software or that the pc is a member of company domain... I thought you have solved the problem, because suggested test case ​http://www.virtualbox.org/download/testcase/VirtualBox-4.2.19-88838-Win.exe runs without any errors. What is happening?

[yefkov]

The same issue with older version (4.1.6): Ticket #9880

[ScottG]

I am having the same problem, I also have Win 7 Pro 32bit. I have tried to install both 4.2.18 and 4.3.0 and I get the same errors. Virtual box will not start.

I keep all my downloads and have an older version 4.2.4. I installed this one and it starts with no error.

So, I've got it running.
I have removed the following registry keys:
HKEY_CURRENT_USER\Software\Classes\CLSID\{00020420-0000-0000-C000-000000000046}
HKEY_CURRENT_USER\Software\Classes\CLSID\{00020424-0000-0000-C000-000000000046}
I don't know what consequences for system this action may carry with. So export before deleting.
Also I've found out that the error

ERROR [COM]: aRC=E_ACCESSDENIED (0x80070005) aIID={fafa4e17-1ee2-4905-a10e-fe7c18bf5554} aComponent={VirtualBox} aText={The object is not ready}, preserve=false

is still there. Though it occurs AFTER I close VirtualBox GUI. Therefore I suspect that this error is not the root cause.

[MarkG1234]

Thanks yeflov, this fixed things for me.

I deleted those reg keys, uninstalled VirtualBox, did a registry clean with CCleaner, rebooted, reinstalled Virtualbox 4.3 No errors at all, not even on closing.

This is the first post 4.2.17 build that's ever worked for me, besides the 4.2.19 test build that's now removed..

Guessing this gives the devs a way forward for fixing this properly.

This is a COM class registration. This might be interesting:

Thanks @yefkov. I suspected that the key could be different on my system. I uninstalled VirtualBox, exported the entire CLSID tree, and deleted it. I also ran CCleaner and fixed any registry errors. Rebooted and installed VBox 4.3. Still received the error. I then uninstalled VBox 4.3 and installed my older version 4.2.4. Unfortunately, it now also receives the error.

I tried to import the CLSID tree I exported, but there was no change, older version still does not work. There may have been some other keys in the registry that allowed it to work. Unfortunately I did not make a back up of the reg errors found by CCleaner before fixing them. So it looks like VBox is out of commission for me.

Hi Guys,

same Problem here. I think it has to do with the user rights! I have several user accounts on one machine and some work with no error.... I tried to find out if there is a difference between the accounts, but i can´t find any differences except the user names. I also find out that my installation works when i set it to Compatibility mode "Start as Administrotor", but a prompt will show. When i start it in Compatibility mode "Windows Vista (SP2)" it runs with no prompt and no errors. That works on all my user accounts on that machine. Can anybody confirm that ?

[hoelle]

I found a solution that worked for me after comparing two ProcMon Traces of a working and a broken installation:
HKEY_CLASSES_ROOT\CLSID\{00020420-0000-0000-C000-000000000046}\InprocServer32 and
HKEY_CLASSES_ROOT\CLSID\{00020424-0000-0000-C000-000000000046}\InprocServer32

The (Default) entry said "oleauth32.dll". After changing that to "C:\Windows\system32\oleaut32.dll" in both locations it worked again!

EDIT: registry path was wrong (was HKEY_CURRENT_ROOT\Classes\CLSID)

[ScottG]

OK I tried an experiment. Since I do not have those CLSID keys in my HKCU tree I tried creating them based off HKLM. I got further now. Now the GUI manager opens. I am getting some errors, but it starts up. It looks a little like those keys are not being created on my system for some reason. I still have to test more. I will update once I have more information.

Thanks @hoelle. I have tested a bit more. I cannot get VBox 4.3 to work even with those keys added to HKCU. I can get an older version to start up the GUI, however I get abort errors on VBoxTestOGL.exe. Windows reports that the .exe has stopped working. I receive about 3 error on start up. I also cannot start up a VM that has 3D acceleration enabled. The error indicates errors with the host graphics drivers, which makes some sense as the earlier error was a display error. I am going to try reinstalling/updating my display drivers and see if this fixes anything.

UPDATE: Updating my video driver has fixed the abort errors. I can now start VBox 4.2.4 GUI with no problem and I can also start VMs with 3D acceleration enabled. I tried to uninstall 4.2.4 and install 4.3.0, however I still receive the original error. At least 4.2.4 is back and working again. For the devs, my graphics card is a Radeon HD 3450, driver is ATI Tech version 8.640.0.0 if that helps out any. Let me know if any additional info can be provided that may help.

[ericcire]

I was stuck with this problem for over a month, since 4.2.18. After changing these 2 keys by adding full path to oleaut32.dll. Virtualbox 4.3.2 started normally.

Before this, I was unable to run VirtualBox whether as administrator or not.

Thanks @hoelle.

Got this same problem on Win7/32bit host since VB 4.2.18. The 4.2.19 build worked for me too. The registry correction did not work for me. Now solved using Compatibility mode: any compatibility mode lower than Windows 7 solves the issue (now I'm using Vista SP2 compatibility mode and all seems working correctly).

Hope this helps.

This helps hugely - I was having a mild panic that perhaps an AV or firewall setting was causing the issue. This has happened since my last set of Windows Updates. Unfortunately, I can't see what they are because of group policy restrictions!!

YES! I have compared my two HP laptop: the one where VB is running fine doesn't have any of these xyz2042* clsid! There are 6 of them:
from [HKEY_CURRENT_USER\Software\Classes\CLSID\{00020420-0000-0000-C000-000000000046}]
to [HKEY_CURRENT_USER\Software\Classes\CLSID\{00020425-0000-0000-C000-000000000046}]

I have googled the first of them and found references only to the classic location HKEY_CLASSES_ROOT\CLSID\ (so not inside the account's registry!) and indeed both the laptops have them in the correct location.

I have exported all the 6 from HKEY_CURRENT_USER\Software\Classes\CLSID\ location (just in case), from the laptop where VB wasn't running and then I have deleted them.

VB is now running fine even without reinstalling it! I have only removed the execute in copatibility mode setting! I'm really happy now!!!

[Frank Mehnert]

Can anybody of you tell me how you found that removing some registry keys fixes the problem for you? Are these keys documented?

[jeremy.bass]

ok few things to note on this, looked to one system for these sets of keys and first they are on both, second they have data like PSDispatch and PSTypeComp .. this leads me to believe that these keys you are deleting would be for photoshop or powershell but not for this. Take note BOTH SYSTEMS HAVE THESE KEYS in the reg, both working and nonworking system. Can some one confirm that this is an effective course here. I really need to get working now and this is holding me back.

Side note here, this seems to have be after the last update of windows, not last update of the virtualbox. With that I'm thinking that the best course here is not hack up the reg but look to what changes beside just this app? I'm looking at updates like

KB2862152 ​http://support.microsoft.com/kb/2862152

or something. Anyone run down this route?

PS means Proxy/Stub and has nothing to do with Photoshop or PowerShell. It's a part of COM-mechanism. PSDispatch is a Proxy/Stub class for IDispatch interface. PSTypeComp is for ITypeComp interface.

Fehler: Cannot create Com Object

Fehler: Callee RC: E_NOINTERFACE (0x8004002)

1. Ursache: defekte CLSID {Anwenderfehler}
2. Ursache: Programmiererfehler {schlampigkeit}

Zu 1: Aufbau CLSID:

Key{SID}, SubKey {z.B. InprocServer32},

Value{Standard=REG_SZ: Pfad und Name zu einer .exe oder .dll}

Beispiel: C:\Program Files\Java\jre7\bin\jp2iexp.dll

Wenn hier als Wert kein gültiger Pfad vorhanden ist, führt der Aufruf zum Fehler

{Bei registrierten .exe oder .dll reicht auch der Dateinamne, ein Pfad ist dann nicht nötig}

Besipiel eines fehlerhaften Value:

rEGu-WdtJ=mq=M,JfU4SPackager>M5KDYSUnf(HA*L[xeX)y

Typische Ursache:

beim Installieren von Virtual Box, VM-Ware oder VPN-Software wird eine virtuelle Netzwerkkarte angelegt. Dies schlägt fehl, wenn das Netzwerk abgeschaltet ist

Dafür Ursache: Ein Computer {Notebook} ohne Netzwerkverbindung

• kein Kabel angeschlossen, mit W-Lan nicht verbunden

Dann schaltet Windows das Netzwerk ab {Stromsparfunktion}

Zu 2. Deinstallieren / Update

Beim Deinstallieren werden die CLSID nicht gelöscht. Sie verbleiben und werden weiter verwendet Eine neue Installation legt eventuell richtige CLSID an, diese sind aber in der Reihenfolge in der Registry später, als die defekten CLSID und werden nicht verwendet.

Lösung:

Alle HKCU CLSID löschen, die keinen gültigen Eintrag haben {Pfad, Dateiname} Ein Risiko oder Folgefehler entsteht dadurch nicht, da diese Einträge ohnehin nicht funktionieren.

Hello everyone, kindly find attached the error i get whiles launching my virtual box and assist. thanks in advance

[Paradox]

I have been having this problem with any version I tried to install recently (4.3.24, along with several older versions).

I tried removing the registry entries given above but this didn’t work for me.

I did find a solution that may help someone else in the future though.

In the registry keys:

HKEY_CLASSES_ROOT\CLSID\{00020420-0000-0000-C000-000000000046}\InprocServer32

through to:

HKEY_CLASSES_ROOT\CLSID\{00020425-0000-0000-C000-000000000046}\InprocServer32

I had 3 values:

(Default) = “C:\Windows\system32\oleaut32.dll”
ThreadingModel = “Both”
InprocServer32 = [lots of random characters]

I tried deleting the InprocServer32 value from each sub key and this fixed the problem for me.

[bird]

We've had a look at a similar problem recently. What it looks like is that some program installed a OLEAUT32.DLL update aimed at Windows NT 4 and Windows 95 on a newer system, slightly messing up the factory OLEAUT32.DLL installation with these HKEY_CLASSES_ROOT\CLSID\{00020420-0000-0000-C000-000000000046}\InprocServer32\InprocServer32=[random looking characters] values.

The next 5.1 build contains code to try help detect this problem and identify which program is causing it, so that you can uninstall it.

We've found two such programs so far, "Dell Resource CD" / "Dell Precision Resource CD" and "GIGABYTE VGA @BIOS". Uninstalling the Dell one certainly worked on the 32-bit Windows we tested it one. The GIGABYTE thing was observed on a 64-bit Windows 10 and wasn't actually causing any visible trouble.
