Visual Studio 2008 give error of component not found

I'm been using VS 2008 "forever". Rebooted yesterday and now I get an error that says a component can not be found. This is on the devenv.exe executable and is the first thing that is displayed.

I've reinstalled, I've uninstalled and installed VS2008 twice and still get the same error.

Searching on the net shows people having a similar problem with a missing alt dll, but I don't have VC++ loaded and that dll is not missing. Have ran the depends.exe and the only missing dll is dwmapi.dll, which isn't even needed on a Windows XP os. Tried using /safemode and it still fails. Using /log flag shows nothing too.

I need some more ideas or a way to find out what exactly is missing.

Thanks Dwight

edit: the error was that atl90.dll was missing in one of the 开发者_如何学CC:\WINDOWS\WinSxS\x86_Microsoft.VC90.atl* directories.

Don't even hav vc++ added.

Not a lot to go off of from your question, but have you tried:

• If Vista/7: Launching VS in administrator mode (via the shell link properties)?
• Turning off any Anti-Virus software?
• Clearing the system event logs and temporary directories?
