Hello Edwin,

Thanks for your reply. I searched both of those and did not find the bundle there. I did find it in C:>Users>{Username}>AppData>Local>PackageCache for some reason. I’m new to the world of installations so I don’t know how it ended up there but will be investigating it. Again, thank you for the reply.

On 64-bit systems you will find the bundle entry under HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall.
On 32-bit systems you will find the bundle entry under HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall.

I typically look for the information by comparing Publisher and/or DisplayName (and optionally BundleVersion). Something like the following

Get-ItemProperty -ErrorAction SilentlyContinue -Path HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*,  HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\* | Where-Object { $_.BundleProviderKey } | Where-Object { $_.Publisher -match 'ActualManufacturer' } | Where-Object { $_.DisplayName -match 'ActualProductName' } | Where-Object { $_.DisplayVersion -match 'ActualVersion' } | Select-Object -ExpandProperty QuietUninstallString

I'm looking for an entry containing a BundleProviderKey value to ensure I'm looking at bundles. Then I make sure the Publisher, DisplayName, and DisplayVersion match what I expect to find. You can remove one or more of those Where-Object cmdlets if they're not helpful. Alternatively, you can replace them with any other condition that makes more sense for your use case. Finally, I expand the QuietUninstallString to get a command I can execute to uninstall the bundle without showing the UI. Alternatively you could expand UninstallString instead to show the UI.

Hello All,

I am unable to find the bundle executable. I have tried both the locations: HKEY_LOCAL_MACHINE:\Software\Microsoft\Windows\CurrentVersion\Uninstall  AND  HKEY_LOCAL_MACHINE:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall. Currently, I can only uninstall/repair in the ARP but would like the option to do it programmatically. The MSI's and prerequisites that the bundle installs are, however, located in both the ARP and the folder/s mentioned above. Where can I find the executable for the bundle so I can run a command such as "C:\....\BundleName.exe -uninstall"
