Upgrade multi-instances

Postby vsjb_yllim » Thu Sep 28, 2017 12:07 pm

Good day,

I'm new to installer script, especially MSI. I've been testing for couple of days and reading the forum again and again, yet I'm still stuck in below situation:
  1. I manage to install multiple instances with each has its own Product Code.
  2. Each instance could be uninstall from "Program and Features" accordingly.
  3. If only 1 instance installed, upgrade works fine with latest files being copied.
  4. Problems when upgrading one of multiple instances:
    1. Files under the selected instance has been removed after "Remove MSI Package".
    2. No file is copied after "Apply Install".
    3. Uninstall works fine for rest of the instances except the first installed instance.
I've tried as per suggested in https://www.installaware.com/forums/viewtopic.php?t=3609 but luck is still not on my side. Perhaps anything that I need to take note while running "Remove MSI Package", "Apply Install" or should I use other method to install these new files? Any advice and very much appreciated and thanks.
