ReSharper won't load when starting Visual Studio 2008

Question

When I started Visual Studio 2008 I got an error on the .Net Framework. All my projects wouldn't load and there was een error with ReSharper 6 as well. Which one I sadly don't remember.

After fixing the .Net Framework, I rebooted and all my projects loaded again.

However, my ReSharper 6 wasn't starting. When I go to Tools -> Options -> ReSharper I see "An error occurred loading this property page." So Visual Studio knows it is installed.

I've tried removing and reinstalling ReSharper 6 but that didn't work.
Anyone got any ideas?

Answer 1

Perhaps you still have corrupt settings or not everything has been resolved when you "fixed the .NET framework"

If you can get to the ReSharper options, it might be worth clearing the Cache (General tab - Clear caches)

You can also access ReSharper options via Tools -> Options -> ReSharper instead of the ReSharper menu, you have the option in here too to Suspend it.

if not;

Try resetting to the default settings

 devenv.exe /resetsettings

You could also run it up in safe mode first, although since this will disable ReSharper it's unlikely to prove anything

devenv.exe /safemode

Failing that, an uninstall of ReSharper first, Then VS - then a re-install of both in the opposite order would be my only other advice.

I've used

devenv.exe -ResetSkipPkgs

This allows to show errors. Using

devenv.exe /log

Error was logged at

<USER FOLDER>\AppData\Roaming\Microsoft\VisualStudio\10.0\ActivityLog.xml

So I've discovered

Extension will not be loaded because an extension with the same ID
'JetBrains.ReSharper' is already loaded at C:\Program Files x86)\JetBrains\ReSharper\v6.1\Bin\...
C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\JetBrains\ReSharper\v8.0\

CreateInstance failed for package
[JetBrains.ReSharper.Product.VisualStudio.v10.0.Package, Version=8.0.14.856,
Culture=neutral, PublicKeyToken=1010a0d8d6380325]

It was a gone wrong installation of ReSharper version 8.0. I removed this folder using Administration privs:

C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\JetBrains\ReSharper\v8.0\

My 2 cents

I had a some what different issue, but I thought it was worth sharing. I installed Resharper 9, but my Visual Studios still thought I had some older version of Resharper installed. If you go to Tools then Options , you may see Resharper and Resharper Ultimate . I had to find the old version of Resharper my Visual Studios thought I still had installed. Specific instructions:

1. Close Visual Studios
2. Download and install old Resharper
3. Uninstall old Resharper
4. Open Visual Studios, then close it (for some reason, it wouldn't work for me unless I did this step in between)
5. Install new Resharper
6. Open Visual Studios
