I'd like to take a look at the FlashInstall.log files. On a 64-it OS the files are located at C:\Windows\System32\Macromed\Flash and C:\Windows\SysWOW64\Macromed\Flash. Please upload the files to cloud.acrobat.com using the instructions at The specified item was not found. or to some other file sharing service of your choice that does not require log-in access. Post the link to the uploaded files in your reply.
