When trying to install Quickmap, you may get this error:
Error 0x80070643: Failed to install MSI package.
Error 0x80070643 indicates that there is a problem with the .NET part of the install. .NET may be corrupt. .NET is a Microsoft component that is used by Quickmap and a variety of other programs, and is a prerequisite that is installed by the Quickmap installer if you don’t already have it (or are running an old version).
To fix .NET install issues:
- Run the Microsoft .NET Framework Repair Tool
- Restart your computer
- Download and install the latest version of .NET
- Reboot your PC
- Try installing Quickmap again
If you have trouble with .NET (steps 1 – 4, prior to attempting to install Quickmap), you may need to reinstall your copy of Windows.
