Upgrade Failed - "Cannot Access Kernel Driver"

[dfulton]

I am running Win Vista Ultimate 64 bit. I have been running Virtual Box for months. I upgraded to 2.2.0 and have been unable to get the program running. I keep getting the error message: "Cannot Access Kernel Driver". I have done a repair as was suggested in another post. I have tried, complete uninstall and re-install. Still I am unable to get it running on Vista 64. Any help would be greatly appreciated.

You need to give more details of exactly what you have done and what the result was.

Just last weekend I upgraded from 2.1.4 to 2.2.0 on a Vista 64 host. I have not had any problems.

I downloaded the new version and ran the install. In went through the install process with no error messages. Then when I try to start my Ubuntu guest I get the error message.
