Windows XP: "Connection failed press Ok to relad the installation process" attempting to install Flash Player

I'll need to review the installation log files to troubleshoot the error.  Please provide the following log files:

• FlashInstall32.log saved at C:\Windows\system32\Macromed\Flash\FlashInstall32.log
• Adobe_ADM.log and Adobe_GDE.log files saved at C:\Documents and Settings\<YourUserID>\Local Settings\Temp\Adobe_ADMLogs
  • Note: The Local Settings directories may be hidden see Display hidden files and folders to view hidden folders.
• Upload the files to cloud.acrobat.com/send using the instructions at How to share a file using Adobe Document Cloud
• Post the link to the uploaded files in your reply

I don't recommend using the content debuggers suggested by the OP.  These are for developers to debug their code and, depending on how the content you are attempting to view is coded, will make the non-developer viewing experience unpleasant and it'll continuously display errors.

are you using any proxy?
