I am getting this error during compilation of my code in a XP Pc. I have only NX installed for gcc.

process_begin: CreateProcess(C:\Projects.Local\Embedded\SB\Core\Main\Tools\DiagUtil.com, ../../../Core/Main/Tools/
DiagUtil.com /DiagCodesFile:DiagDef.h /Module:PPDA /UseClass:Pack /ImpXls:../../../Core/Main/Config_Files/
CommonDiagnostics.xls /ImpXls:C:/Projects.Local/Embedded/SB/IOPack/Main/PPDA/Config_Files/PPDA_Diagnostics.xls /
ExpDiagCodes:C:/Projects.Local/Embedded/SB/IOPack/Main/PPDA /ExpDiagMsgs:C:/Projects.Local/Embedded/SB/IOPack/Main/PPDA,
 ...) failed.
make (e=5): Access is denied.
make[1]: *** [diagsrc] Error 5

Please suggest.
