Hi, please make sure, that "python.exe" equals the id-tag of that file in your setup.
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.
