使用 InstallShield 创建的 Setup.exe 文件已成功安装，但应用程序没有更新，它保留以前安装的版本

Question

Problem I'm facing is that Setup.exe with new app version is successfully installed but previous version that exists is not upgraded.

When I run the application it opens in previous version(4.5), but in control panel next to the app name stands new application's version number(4.6). There is no two instances in Control Panel.

Setup.exe file is created using InstallShield 2018 Express. In Upgrade Paths I've added new path created from my previous setup.exe file. The upgrade code is same as for previous versions, and in General Information I've updated the Product Code.

For "Max Version" number I've tried with 4.6, 4.5.1, 5.0 and allways the same problem appears.

"Include Min Version" is set to No

I've done this several times in the past successfully but for some reason this time it doesn't work.

With same setup.exe file application is successfully installed from scratch, but when previous version exists it doesn't work as expected.

None of the solutions I found online worked for me.

It seems to me that your main application (executable?) is not getting upgraded. Make sure that you're logging the install. Then after the install completes search the log for the Component GUID of the executable not upgrading to search for clues.

One other thing to check for is a pending reboot. If the application was in use it may not upgrade until a reboot happens.

I have solved this with click on "Resequence RemoveExistingProducts" button in "Upgrade Paths" tab.

Somehow this order of installing/removing product was changed.
