I simply need to install a program into my computer, but whenever I try to it says, "Another installation is in progress. You must complete that installation before continuing this one". When I looked up how to solve this, a post said:
On the Registry Editor (regedit.exe), navigate to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\InProgress and delete the entries you can find.
I accessed this folder, but the only program there was (Default) REG_SZ I tried to delete it and a pop up said something like, unable to delete value. What do I delete, or how do I fix my original problem?
