Maybe this is the problem:

Q: I have just installed Gamestudio on another PC. Now I get an error message (Error E1513) as soon as I start any project. 
A. Check how the DEP (data execution prevention) is set in your Windows configuration. Go to My Computer / Properties / Advanced / Performance / Settings / Data Execution Prevention, and make sure that it's in its default setting ("For essential Windows programs and services only"). A wrong DEP setting prevents on-the-fly compiling lite-C or C-Script source code.
