Hello. I've worked on an XP PC with AVR Studio 4 so far. On my new Win7-Pc I installed AVR Studio 5 latest version. Importing the Studio 4 projects makes Studio 5 without error messages. However, if I want to compile the project (via build-compile), the error message comes that the AVR-GCC.exe is not found. For me synonymous understandable, because Studio 5 is still looking for the old path of the Xp-Pc. Can someone tell me what I have to do, that after the compile import also the new compiler is used? I want to leave all settings, only possibly change the c-code if necessary. Thanks in advance.
