While upgrading to the April 5th nightly build, the installer did something I hadn't see it do before. It displayed a maintenance installer dialog with some place-holder text, but the buttons wouldn't enable. So I un-installed completely and re-installed.
Now, when I load VS 2008, I get an error dialog.
ReSharper Fatal Error
JetBrains ReSharper 4 add-in could not to load the supplementary package 0c6e6407-13fc-4878-869a-c8b4016c57fe.
It is recommended that you repair the product installation.
I've tried repair, and also uninstalling and reinstalling, but I still get the error. I also get the error if I go back to 4.0.769.
I'm running VS 2008 (.NET 3.5 installed) on Vista Business SP1. Anybody have a suggestion on how to fix this?
