my project build with x86 version, and i used InstallShield 2010, this issue is for WCL i think!, not InstallShield... becuse i used it before with old version x32 of WCL,
when you release new version i replace new version of this WCL, and this error i see it.
other things i must say InstallShield will automatically analyze files, when InstallShield want to add "Visual C++ 10.0 CRT (x64)" this mean WCL need "Visual C++ 10.0 CRT (x64)"...
