I'm getting a weird problem with Visual Studio 2010 Premium. I use two PCs, on the first there is no problem on the second the "Solution Platforms" popup menu disappeared, the configuration is the same (Windows 7 x64). The problem occured when I opened a project from a mercurial repo, I was not able to restore the popup. I reset the Visual Studio settings and done a Repair from the installer. No change. If I create an blank project (framework 2.0, 3.0, 3.5, 4.0) the "Solution Platforms" popup is still missing. Also if I change the target platform with Build --> Configuration Manager there is no effect on the build (no compilation for x86 for example).
Any ideas (no full reinstallation please ) ?
thank you.
