Please find attached a screen shot of the message I receive after the download of the latest window version.
OS XP Home SP3
Sorry, there is no screenshot in your post. (You need to login to the forum, and upload the screenshot using the camera icon.)
Try the following: download the offline installer from http://helpx.adobe.com/flash-player/kb/installation-problems-flash-player-windows.html#mai n-pars_header (under the heading Progress bar hangs...) and save it to disk, then right-click on the downloaded installer and select Run as Administrator.
If that still does not solve your problem, try a clean install as described in http://forums.adobe.com/thread/928315
Thank you Pat, but the download did result in the following message:
I could not load the screenshot as it was not accepted even though it was a small file.
That means you didn't do the clean install; for some reason the installer cannot remove that file.
