I tried this with the value: false but it is still not working. I cannot install it because of compatibility reasons. I deinstalled it first, added this key and restarted FF and then installed the add-in without success.... This is the version I'm using:
Actually I got the same error upgrading to Firefox 3.5 just now (August 4th, 2009). Once I restarted Firefox then went to logmein.com and tried to connect, their servers told me I needed to install a new plug-in and that worked.
I had to go in and manually copy the new 608 npRACtrl.dll into the C:\... location above for the new plugin to be used and for the nagging to upgrade to stop... and for the firefox crashes to stop... looks like... for now.
Please advise how we can do upgrades in the future... without messing with the filesystem so much... and doing it the RIGHT way!
