Hello,
I am receiving the following error when attempting to upgrade an application from an MSI:
"DEBUG: Error 2756: The property 'INSTALLLOCATION' was used as a directory property in one or more tables, but no value was ever assigned."
Can someone tell me: Is it complaining that it can't find the "INSTALLLOCATION" value for the already-installed version of the application, or is it that the new MSI doesn't define that variable?
Either way, is there a registry trick or some other method I can use to get around this error?
