Install/upgrade not working. Missing PMS.MSI

Don’t know if you managed to get past the hurdle

Have been looking into all the logs - the issue is that it is failing to remove what it believes a previous installed version - that it cannot find

Action start 14:41:31: RemoveExistingProducts.

It has not logged what version it is and it’s package name is null !

What we could try is entering that product code into the Microsoft troubleshooter for install / uninstall

Selecting troubleshooting Uninstalling first


Then selecting Not Listed

and then on this screen entering the product code that shows in the above error log
{527EC40A-78B9-46DE-84BB-ADB8A3C51833}

and see if after this, you can install

If not, get all the new logs and zip and attach !
