Greetings!

Upon starting FG yesterday i started getting this message as seen in the picture. Anyone that can explain what this is or why it happens? Tried clearing the cache and reinstalling FG to no avail. Thanks.


Regards.

Welcome to the FG Forums!

This is the same error as reported here: https://www.fantasygrounds.com/forums/showthread.php?86825-FGU-Web-Browser-issue-after-5-1-4-update

Are you running Fantasy Grounds as "Administrator"?

I was getting the same error. FG and FGU have run flawlessly on my machine since 2014. I went in and ran the updater "FantasyGroundsUpdater.exe" from the direct link and it triggered something as it successfully updated. FGU loaded normally and ran updates as expected again after that. Really odd.
