Hi All,
I have created an msi installer using advanced installer. I have given Product id as say "PROD_ID1" and Upgrade id as "UPG_1".
Now I have added some new files in the installer and now I changed the version from 7.9.1 to 7.9.2.
But whenever I am running the msi installer via cmd then it is throwing error . (A product is already installed).
Can someone point out what I am missing.
I have kept Product id and upgrad id same.

Re: Unable to upgrade created msi from 7.9.1 to 7.9.2
Hello and welcome to our forums,
Windows Installer can upgrade the original package only if the modified one has a higher version and a different Product Code. The Upgrade Code must remain the same.
If you want to create a new version which will upgrade the old one, you can follow the steps explained in the Upgrades article.
In your case, you need to generate a new product code for the second version.
Hope this helps! Let us know if you have any questions.
Best regards,
Liviu
