Another version of the product is already installed...
Hello!
There are 2 situations with Installshield when I get the "Another version of the product is already installed " error.
1. I'm building the same Installshield-project as both single MSI and as single EXE. Running EXE. The installation is succeeded. And then I'm running MSI and getting "Another version of the product is already installed " error.
2. I have built a single MSI file for a project.\ Running MSI. The installation is succeeded. I change field "Product Version" from 1.00.000 to 1.00.001. Build MSI. Running this new versioned MSI. That leads to "Another version of the product is already installed " error.
The question is: 1. How to make MSI-s run correctly in both cases?
My problem is partically solved. In the Releases View I set the following details of the "Project_assistant" item:
Package Code > I generated new GUID Generate Package Code > No.
It must have been done because of it's not allowed to use 2 different msi-s with the same Product Code but different Package Codes.
And now I face the new problem. The MSI-installer with a newer version doesn't show message like 'Do u wanna upgrade to new version?'. It runs like the standart way with 3 types: remove, repair, change. And doesn't update the installation.
Lenwin, thanx. Your variant works, but not normally: 1) While upgrading old files are not uninstalled 2) User wants to run .msi-file, but not command-line. Is there possibility to load this command into msi?
