%1 is not a valid Win32 application."" />


When running setupwin32.exe to install the Unicenter Workload Control Center, I receive the following error:

"CreateProcess failed ==> %1 is not a valid Win32 application."


This error was a result of the Windows environment variable TEMP being set to a value unknown to the ISMP installer (in this case the value was %TEMP%).

To correct this value:

  1. Start -> Settings -> Control Panel -> System -> Advanced -> Environmental Variables.

  2. Set the value for TEMP to a real directory on the machine:

    C:\temp (as an example.)

  3. Then retry the command.
