When installing Quickmap, you may get this error:
Setup Failed
One or more issues caused the setup to fail. Please fix the issues and then retry setup.
For more information see the log file.0x80070666 – Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this produce, use Add/Remove Programs on the Control Panel.
This occurs because you are trying to install Quickmap Version 8 on a machine that has a minor version of Quickmap version 8 that is higher than the version you are trying to install.
If you are installing from a network, the QSetup.exe file on the server is not the latest one. To fix this, download the latest version of Quickmap and copy the resulting QSetup.exe onto your network location, replacing the older QSetup.exe file.
