I first came across this issue when helping a customer uninstall Site Recovery Manager last year and wanted to blog about it but because I was pretty busy it totally slipped my mind….. until today!! I’ve been cleaning up the Solution Centre at MTI and tried to uninstall SRM for a new build…. and came across the same Windows User Access Control error. =)
Turns out that in Windows 2012. even when you go into User Accounts to turn off the UAC, it doesn’t disable it.
There’s a Microsoft Technet article which explains how to edit the Windows Registry in order deactivate UAC.
- Go to Start > Run, type regedit and click OK. The Registry Editor window opens.
- Navigate to HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows > CurrentVersion > policies > system.
- Right-click EnableLUA and select Modify.
- In the Edit DWORD window, change the Value data from 1 to 0.
- Restart the Windows machine and re-run the SRM uninstall program.
