Fix: Installing Visual Studio 2012: Setup Blocked, Another Setup Is Already Running

Are you trying to install Visual Studio 2012 but you get the error “Setup Blocked”? If so this is most likely because another setup failed to properly close / remove a registry entry

1. Step This is what the error will typically look like:

Another Setup Is Already Running Please Wait For It To Finish Before Trying Again.png

2. Step Go to the Start Screen and hit CTRL + F

3. Step Enter regedit.exe and in the left pane click on the item that appears

4. Step Uncollapse HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager

5. Step In the right pane you will see an item called PendingFileRenameOperations with a path to AppData\Local\Temp and a stuck .tmp file

When opening it you might see something like

6. Step Delete the key (right-click – Delete)

7. Step Now open vs2012_webexp_enu.iso to start the install again

8. Step In my case I was greeted with a insufficient disk space error, unfortunately Microsoft does not allow to install on another drive than C and the browse button will be greyed out. I noticed this behaviour in other apps like Office 365 as well and it is a very frustrating “bug” – it might be designed that way by design, but installing on another drive is so 1999
