Uninstall all previous versions of projectwise?

Question

Within my company there are many computers who have gotten behind on bentley updates. In order to get everyone upgraded to the newest releases, I was wondering if there is an uninstaller script or .exe that will remove any previous version of projectwise or microstation in particular. I will post any findings that I come across or create myself to help others.

I discovered a very easy way to uninstall any version of projectwise. Since the .exe's are just calling a bunch of .msi installers, all of the uninstall strings are located on the computer and realatively easy to find with powershell. The script I wrote is: 
 
$programs = Get-WmiObject -Class Win32_Product | Where-Object { $_.Name -like "Projectwise *" -or $_.Vendor -like "Bentley *" } 
foreach($program in $programs){ 
$program.Uninstall() 
} 
 
This iterates over the list of found installed programs that match the search conditions ( a name that starts with projectwise or a vendor that starts with bentley) and uninstalls them. This version will also uninstall microstation and most of the pre/post reqs that come with it. Hope this helps someone out there.
