Unable to repair or uninstall AEM. Error 1722 Missing FileSystemBrowser.dll
Hello. I am unable to repair or uninstall AEM from my machine after neglecting to enter the license key when installing.
I get the following error:

I have tried reregistering the dll. I took a copy of the dll from machine where AEM is known to be working.
I used the Cleanup tool offered in other solutions I found on this site.
Anyone have solution for this issue?
