(WiX) - Auto-generate GUID with pre-build event (heat.exe)

i've made a pre-build event for my directorys/files. now its creating the source.wxs fine, but there are only 'GUID="*"', so now i get compiler error because it is not mapped on ProgrammFilesFolder, but every component needs an unique GUID:

Path" %SystemDrive%\st /MIR
"%WIX%\bin\heat.exe" dir %SystemDrive%\st -dr INSTALLDIRECTORYFOLDER -cg    SourceComponentGroup -var var.SourcePath -ag -out "$(SolutionDir).\Setup\source.wxs"

result:

<Component Id="cmp97CD2699CFD0E466AE00E9EE0BC75B3D" Directory="dirE9158D60656EC6CD461378A2C8EDC064" Guid="*">
     <File Id="filD6533D5A559BC86E4704F435FEEE2A5A" KeyPath="yes" Source="$(var.SourcePath)\test1.txt" />
</Component>

Are there any parameters i can change to get the desired effect? i couldnt find any documentation about the parameters.

Without knowing the exact compiler error I can't say whether this will fix it, but to get heat to generate the guids for you, you need is the -gg switch rather than -ag. FYI the commandline options can be found here.
