When I try to install Keyman Desktop 14 my McAffee anti virus refuses to accept it and even deletes the msi file from the downloads. What’s the story?
It will be a false positive. We have had some trouble with this with some antivirus software. Can you try and submit the file as a URL to them as a false positive?
The URL for the latest of Keyman Desktop 14 is https://downloads.keyman.com/windows/alpha/14.0.172/keyman-14.0.172.exe
Note that VirusTotal reports the installer as clean: https://www.virustotal.com/gui/file/c387aaa8a084f4e0a8483ae9e9ba5dc4a4a55db3c38c0227ae0aedef7ac52af4/detection
McAfee reports a false positive. You can flag it to them with the link above.
