A newer version of this software is already installed

Post by Patrick9999 »

Product: PowerShell Studio 2022 (64 Bit)
Build: v5.8.213
OS: Windows 10 Enterprise (64 Bit)
Build: v10.0.22000.0


*** Please add details and screenshots as needed below. ***

I am working on two different applications that are installed on the workstations via msi packages, for both the packager file version and Product version are modified to be able to upgrade. the installer Product version is also modified as with the packager. The new versions are installed but when application 1 is installed on the workstation, the second application cannot be installed because it says "A newer version of this software is already installed" and if application 2 is installed , we cannot install application 1 (with the same error:A newer version of this software is already installed..., they are two completely different applications. What am I doing wrong?

Please zip the .psbuild files of both projects and upload them here: https://www.sapien.com/support/upload
I'll have a look.

The upgrade ID in both your files is identical:
UpgradeGUID={6054CD98-10D9-455D-A3E5-60D4DCCC4652}
This tells Windows Installer that this is the same product.
Most likely you got there by copying an entire project including the .psbuild file or by just copying the .psbuild file.
Generate a new GUID or use this one
{7BB0CB90-365D-48B9-880A-06941D8D4609}
in one of your files and the problem will go away.
