I've seen lots of posts where people can't get LogMeIn to work using Google Chrome. I've tried to reply to the posts, but some threads seem to be closed, so am posting this here. Hope it helps.
To get Chrome to work with LogMeIn you have to access your computers this way:
1. Log In to https://secure.logmein.com as usual.
2. On your "My Computers" screen click the "Main Menu" link under the computer you want to control (DO NOT click on the big, green "Remote Control" link.
3. Enter your Username and Password for control of the remote machine -- you will then be taken to the "Dashboard" view of the remote machine.
4. On the left-hand navigation menu click on the icon of the computer to the left of the words "Remote Control" (again, DO NOT click on the words Remote Control, but the computer icon to the left of those words.
5. You will now see connection options for remote control. Select "Flash" and you are good to go.
Chrome does work with LogMeIn but the Remote Control does not default to flash for chrome because of the shared plugin ties with Firefox, it tries to load the Firefox plugin and hence your error message.
You have to access this way to get it to work.
The Flash isn't bad for a quick control, but LogMeIn really, really needs to write a dedicated Chrome extension -- especially with Chrome OS launching later this year, GoogleTV and all sorts of other goodness coming out of Mountain View, CA.
Hope this helps,
