I encountered this error using Dev-C++ 4.9.9.2. I noticed that there is an old thread (http://www.gamedev.net/community/forums/topic.asp?topic_id=405648&whichpage=1�) that has a very long and involved solution. I'm not certain, but I think it doesn't have anything to do with Windows Vista. My fix was pretty simple: Menu bar: 'Tools|Compiler Options' Compiler Options dialog: "Directories" tab Directories tab: "Binaries" sub-tab Add path to cc1.exe dir: "C:\Dev-Cpp\libexec\gcc\mingw32\3.4.2" (you'll have to find the dir on your system) Shift+F11 Problem solved! Good luck, Quantium
