Now that is a handful. But there is a solution below for LogMeIn Plugin Crashes Firefox problem...
Finally, I found a solution, I posted it on LogMeIn knowledge base forum, it looks like this:
I had version 1.000.526 or so of logmein for firefox. The new version was supposed to be 1.000.608.
running Firefox 3.6.8 and I was prompted several times to install new
logmein plugin. After doing so, it turns out (had to check extensively
the file system for this) that:
*** logmein downloads and installs the new plugin files into a directory
This is the directory on a faster disk where I moved my xxxxxxx.default firefox directory.
However, mozilla firefox 3.6.8 looks for the plugin in the directory
C:\Program Files\Mozilla Firefox\plugins\npRACtrl.dll
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...
Please advise how we can do upgrades in the
future... without messing with the filesystem so much... and doing it
the RIGHT way!
Oh, I'm posting this on http://annoyances-resolved.blogspot.com so you can add your solution in the comments there if you will!
