To ensure a clean, conflict‑free installation of AVEVA Unified Engineering, remove any previously installed MSIX packages before deploying the required version.
Step 1 – Check for existing installed packages
Open Windows PowerShell and run the following command:
Get-AppxPackage *unified*This lists all AVEVA Unified Engineering MSIX packages currently present on the machine.
Step 2 – Remove existing packages
If any packages are returned, remove each one by using its corresponding PackageFullName value:
Remove-AppxPackage -Package "PackageFullName"Replace PackageFullName with the exact value returned in Step 1.
Step 3 – Install the required version
After confirming that no Unified Engineering packages remain, install the desired release:
Add-AppxPackage -Path "C:\<path>\AVEVA.UnifiedEngineering_XXXX__YYY.msix"Update the path to point to the correct .msix installer.
By removing all previous AVEVA Unified Engineering MSIX packages before installation, you ensure a clean environment, reducing the risk of conflicts or issues caused by remnants of previous installations.
