Scanshare installers are Windows Installer standard installers which are doing several common system operations such as installing services, configuring Windows Firewall rules, doing checks on the system and so on.
The installer process may fail ending in a generic error without much details of what actually failed. This is the typical dialog error message for such cases:
In order to troubleshoot the installer process Windows Installer provides a full detailed log of the complete process, disabled by default.
Windows Installer log can be enabled by running the target installer from a CMD prompt executed as administrator. First navigate to the folder where the Scanshare installer is located and launch the command:
"Scanshare Setup vx.x.exe" /L*V log.txt"
Note that /L*V is all together without any space.
A log.txt text file will be created next to the installer exe file.
