Hi: I've just installed MPLAB 3.99 and am using it with CCS PCM compiler. It appears to call the compiler ok, but then I get an error: Compiling ATGPSE.C: Command line: "C:\MPLAB\CCSC.EXE C:\PROGRA~1\MPLAB\ATGPSE.C" MPLAB is unable to find output file "ATGPSE.HEX". Build failed. Anybody know what I've got set up incorrectly here? Thanks, John Hansen
