Thanks.


Well I copied the 5.0.1 release files from

C:\Program
Files\Oracle\VirtualBox\ExtensionPacks\Oracle_VM_VirtualBox_Extension_Pack

to the location of the installed debug version :

D:\VirtualBox-5.0-amd64-debug\bin\ExtensionPacks\Oracle_VBoxDTrace_Extension_Pack

but I guess thats not correct, as I still get the same error.


Anyway, it works for the newly created vm now.
