Hmm.. wish I could be more help
Haha, don't worry about it, thanks for responding and hopefully the logs you asked about will bring some answers.
I'm not sure if you looked already or not, but the Microsoft forums look to already have this covered:
Didn't see this one before, I'll try installing .NET 4 from standalone installer. I installed it through Windows Update before, maybe the standalone will fare better. The rest I've already tried (uninstall/reinstall/repair for both .NET and VS2010). Thanks for the reply.
*Edit 2* After reinstalling .NET through the standalone installer, the VS 2010 tools for office runtime uninstalled properly. I'm now reinstalling VS 2010, hopefully it works this time.
*Edit 3* Well, this time around using the standalone .NET installer, I got no errors messages during the VS 2010 installation but nonetheless the problem of access denied continues. As with before, the splash screen pops up on launch but then the access denied error occurs and VS 2010 closes.The following is no longer relevant, but I'll keep it up in case it's important later.
*Edit* So I tried to use the standalone installer to repair .NET first, it was successful without errors but the problem didn't disappear. I'm now uninstalling .NET 4, VS 2010, and all related software. I noticed I didn't uninstall ASP.NET MVC 2 Visual Studio tools (or something like that) the first time, so I've uninstalled it this time. It produced some "unknown errors" during the removal but it went through fine otherwise. Uninstalling VS 2010 gave me unknown errors as well this time, and now I'm uninstalling Microsoft Visual Studio 2010 Tools for Office Runtime (x64) and got this error:
Error 1316.A network error occurred while attempting to read from the file: C:\Program Files\Common Files\Microsoft Shared\VSTO\10.0\Microsoft Visual Studio 2010 Tools for Office Runtime (x64)\vstor40_x64.msi
This rolled back the uninstall and it failed, I tried it again just to make sure and it repeated this same error / rollback. Attempted to repair it first, got another error:
Error 1304.Error writing to file: Microsoft.VisualStudio.Tools.Applications.Hosting.dll. Verify that you have access to that directory.
On retry, it gave me another error code (clicked yes out of it too fast, sorry)
Long story short, I'm restarting my computer to see if I can uninstall that last piece and then I'll try installing .NET 4 from standalone + install VS 2010 again.
