(Unable to start debugging on the web server. An error occurred that usually indicates a corrupt installation. If the problem persists, repair Visual Studio installation via 'Add or Remove Programs' in Control Panel)
I saw this happening on a Vista x64 while trying to debug an ASP.NET application and needless to say (), repairing Visual Studio does not help.
This is a misleading error message which might appear when you try to debug an ASP.NET application on a 64 bit OS and you configured your application pool to run a 32 bit worker process; I know it will be changed to a more meaningful message, but I'm not sure about the timeframe (I can't repro so I'm not able to check how Visual Studio 2008 behaves).
What to do then? Check the advanced settings for your application pool and set "Enable 32-bit applications" to "False"
By the way, I was this error in conjunction with this one so pay attention if you're hitting one of the two...

I'm getting a similar error for a Windows Application - any pointers what to look for? Thanks.
Similar problem in vs2008...
No fix for this up to today???
Well, debugging a 64 bit process from a 32 bit one simply cannot be done, there is not much to fix if not, maybe, a more clear error message
For Windows application, inappropriate debugger type (for example debugger type set to script) might cause this problem when trying debug the application. The problem gets resolved by setting debugger type to Auto.
Debugger type can be changed through Project properties -> Configuration properties -> Debugging
