Using msiexec:
To install AutoCorrect using the msiexec command within Windows, the GAC.msi must be used.
When running msiexec, the ACCEPTEULA parameter must be supplied with the value 1,
msiexec /i "C:\Users\USER\Downloads\GAC.msi" ACCEPTEULA="1"
Install with a serial number:
msiexec /i "C:\Users\USER\Downloads\GAC.msi" ACCEPTEULA="1" Serial="123456"
For a silent install, the parameter /qn is used:
msiexec /i "C:\Users\USER\Downloads\GAC.msi" ACCEPTEULA="1" /qn
To uninstall, the parameter /x is used instead of /i:
msiexec /x "C:\Users\USER\Downloads\GAC.msi" /qn
