does VS express conflict with professional?

I just recently installed VS 2008 Professional on my computer and I already have C++ and C# express on my computer. But for some strange reason I can not find the executable for VS professional 2008. when 开发者_运维技巧I go into program files and look under visual studios 2008. All i see is a bunch of tools but no vs 2008 exe

The expression and professional SKUs do not conflict and can be installed together. For the non-express SKU's (i.e. professional) the executable program is named devenv.exe. It will be located under

C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe

Or an a 64 bit machine

C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe

Strange...

have you check the directory C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe?
