Upgrade code problem
I have a vendor msi and i have created transform for customization and deployed to the users.
Now i have to add additional files to the existing package. I have added new files to transform and added upgrade code to uninstall the previous version but the previous version is not uninstalling.
I suspect, the product code and upgrade code of old msi/transform & new transorm are same.
how can i uninstall the old package and install the new package.
