Broken install cannot uninstall or reinstall

[MC]

When I tried to uninstall a 2.0 version of virtualbox it failed. So I used Revo Uninstaller to force it out. At least the network device remained, so the install was definitely botched.

Later I try to install the new virtualbox. At the end it fails "because of an error", and when you click Finish a red X box pops up "Installation of MSI failed! ERROR: 1603"

I think this problem wouldn't exist if you were more independent of windows. Just let people download the program and run it. If the networking breaks then you can deal with it. But the whole installer shouldn't break..

Major because it blocks me from using Virtualbox altogether. Minor because it won't affect many people.

Uninstalling the network interface from device manager did not solve my installation problem like it did for amram99 and JarrettBillingsley.

Does rhe problem still persist using VBox 3.1?

I have the same problem with an old installed Version 2.1.0 and the new 3.1.2. Uninstalling the network interface from device manager did not solve my installation problem, but running MS cleanUp against the old VirtualBox installation and deleting the files in \Program Files was successfull. Now the Installation of VirtualBox 3.2.1 shows no problem.
