Hi !
I am unable to instal LMI AV on several PCs running Windows 10 1909.
The error message in LMI Central is :
Unable to retrieve LogMeIn Antivirus
I was getting this error when trying to install the AV on the same computer I had the web GUI open.
Not sure if that was the issue but that's the only thing I tried differently. Try login to logmein.com from a different computer and try again.
