Explorer.exe is closing during upgrade

Scenario

1. Install Professional 9 with the MSI using your install script.
2. Upgrade Professional 9 to Professional 9.5.1 using the MSI or with a sample command below:
msiexec.exe /i Workshare.Professional.msi" REINSTALL=ALL REINSTALLMODE=vomus ALLUSERS=1 SKIP_UPGRADE_WARNING=1  /L*V logqn.log /qb
3. Notice the following window pops up displaying the following warning message: "Close the following application before continuing the install."



 

Resolution

Workaround

The ‘Restart manager’ is stopping ‘explorer.exe’ because C:\Program Files(x86)\Workshare\Modules\Workshare.RightClick.x64.dll is being held in use by
the process. This DLL is loaded in the memory every time as this handles the Workshare right click functionality.

The workaround is to simply rename this file before running the upgrade. You can do this by running the following command or include it in your install script:
ren "C:\Program Files (x86)\Workshare\Modules\Workshare.RightClick.x64.dll" Workshare.RightClick.x64.old

Alternatively, after a successfull upgrade you can delete the renamed file to tidy up the installation folder:
del "C:\Program Files (x86)\Workshare\Modules\Workshare.RightClick.x64.old"
