Hi All
I have Basic MSI Project where I am trying to uninstall previous version of the product that was created by different developed.
I was thinking using msiexec since it seems to work fine from command line.
I created InstallScript function and set it to:
Synchronous (Check exit code)
Immediate Execution
Always execute
After File Cost
I can see that it starts uninstalling previous product, but it exits before it's done uninstalling.
So my question is how to make sure that LaunchAppAndWait will wait for product uninstall and then continue?
Or if you have better way to uninstall previous product I will be happy to hear it.
Thank you in advance.

MessageBox ("Failed to uninstall",SEVERE);
