When trying to install Quickmap 8, you may get this error after the download is complete:

C:\Users\UserName\AppData\Local\Temp\Quickmap\7z\7z.exe

Windows cannot find C:\Users\UserName\AppData\Local\Temp\Quickmap\7z\7z.exe.
Make sure you typed the name correctly, and then try again.

To complete the Quickmap install, navigate to the Quickmap directory specified in the error (you’ll probably have to type the path into the address bar because the AppData folder will most likely be hidden), then Run QSetup.exe.
