Hi Oli Many thanks for all your help, I really appreciate it, was really stuck!
My final code was this if anyone wondered <CustomAction Id="installMTMAgentService" Directory="pythonD0" ExeCommand='"[#pythonF3]" "[#mCoreF188]" install' /> PythonF3 and mCoreF188 are the correct files for python.exe and service.pyo, i just had to add quotes round it, took a while because the python code needed an environment var, but i created a work around!

If your file-tag looks like this: <File Id='python' Name='python.exe' Source='[INSTALLDIR]bin\' Checksum='yes' /> Then the custom action should look like this: <CustomAction Id="installMTMAgentService" Directory="pythonD0" ExeCommand="[#python] install" /> Oli ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
