VisualStudio 2010安装程序项目向InstallShield无缝过渡

Question

I just installed VS2013. As there is no longer the Setup Project, I installed InstallShield LE. I used integrated import wizard and hoped any newer build would automatically update older versions created with VS Setup project. Well, I used to alter the Product Version, which prompted me to alter the Product Code, and that was it. Now I thought this should work with InstallShield as well, so I updated the product version and manually generated the product code. I had the older application installed and tried to reinstall it with this new IS LE setup. And the result is: There are two applications installed, which have exactly the same name and path (it installed in the same directory), but different version. I can really see 2 programs with the same name in "Programs and Features". I checked the upgrade code, it is the same for both. What did I do wrong?

Thanks

Answer 1

Check the installation type, ie per user or per machine. It must be the same for both versions, otherwise Windows Installer will skip removing the old versions and you will end up with both versions on your machine.

A verbose log created when you install the new version should also be helpful, you can search for FindRelatedProducts and RemoveExistingProducts standard actions in it, to see why the old version is not removed.

Well finally we were able to solve the problem. You need to place an entry to the Upgrades Path section. Oddly enough You need to do this manually and it's not done automatically by the IS import wizard.
