|Environment Variable: MAKEMSI_MM_PRIORITY|
This environment variable is only used by the "MM.CMD" batch file.
This environment variable can be used to run MAKEMSI faster or slower than normal. This should contain the text of any priority switch which is valid on the Windows "START" command, for example "BELOWNORMAL" or the less likely "LOW". You would lower the priority where you know MAKEMSI will take a while and you still want your computer to respond quickly to your "other" tasks.
