Hi,
Do you mean that there are not "Location" and "Solution" in New Project Window while you tried to create new project? To better understand your issue, please confirm the follow information: Which project you tried to create? Did it work ago?
Please install latest services packet for Visual Studio 2005.
If we disable Add-ns (“Tools” | “Add-in Manager”) and run “devenv.exe /safemode”, do we still have the problem? This can eliminate the possibility that third party Add-ins are causing problems.
We also can try to run devenv /resetsettings (Commonly, it makes sense than re-installation) or devenv /setup in Visual Studio Command Prompt.
I look forward to receiving your test results.
