I'm constantly getting this error and can't install Flash. After the installer begins, I just keep getting the message, "Connection failed. Click the finish button and restart the install process."
Firefox (can't find the version #, but it's the most current)
I'd like to get some log files from you to troubleshoot further. Please review the FAQ Where do I find the Flash Player installation log on Windows? Enable your system for verbose logging and run the installer again. When the installation fails, gather the files listed (FlashInstall.log, Adobe_ADM.log and Adobe_GDE.log) and upload them to cloud.acrobat.com using the instructions The specified item was not found. or some other file sharing service of your choosing. Post the URL to the uploaded files in your reply.
Thank you for replying, Maria, but I have found a workaround.
From Mozilla's site, I found a different link to download Flash for Firefox, it worked without any issues.
If anyone else has the same issue, the link is on this page:
Scroll down to "Installing or Updating Flash", below step 3 there's a little box with a link for those who have trouble with the normal link.
