I just downloaded the latest .msi installer for windows 64 bit and I'm trying to install it on a Windows 7 64bit system.
I run the installer and I get this error:
"The following applications are using files that need to be updated by this setup. Close these application etc etc".
And the only application in the list is: "Explorer" (its name is displayed in Italian because my system is in Italian so I'm not sure how it is called in English, whether "Explorer" or "File Explorer" or whatever)
Obviously there's no way I can close it. I've already closed all open file browsing windows but I still get the error.
So basically I can't install 7Zip.
