The ProductCode (ProductID) after Firefox Setup 68.5.0esr.msi is installed does not match to the ProductCode (ProductID) of the Firefox Setup 68.5.0esr.msi. We use SCCM to create the application deployment for Firefox ESR x64 and to install all the endpoints. When creating the deployment, SCCM automatically extracts the ProductCode, and uses the same to detect the presence of the application - if it's not present, it installs. The main issue is that when SCCM checks again the presence after it's installed, the deployment fails because the ProductCode after it's installed is different than what came with the MSI installer. I noticed that this is the case as well for Firefox Setup 68.4.0x esr.msi whereas in the past this was not the case.
