Mirillis forum

I downloaded an updte, but got while downloading the message "Error opening file for writing." C:\ProgramFiles (x86)\Mirillis\Action!\action_x64.dll. I hit RETRY and got the same messsge; so pressed IGNORE and continued installing. When I try to run the program I get the message "Failed to initialize product. Please try reinstalling". I'm going in circles. I have my serial number, as I purchased Action month ago and it had been working pretty well for my son who is the gamer.
Thanks for your help

Restart your PC and install Action! again. Probably action_x64.dll was still in use.
