I hope this screen shot I took and uploaded here as a ".jpg" digital photo image is legible so you can see the problem I'm having trying to install the latest flashplayer version 11.4.400.265.
I have tried running the installation from both Internet Explorer and Firefox browsers, making sure that Java and scripting are enabled in both, per Adobe's troubleshooting page instructions. I also tried downloading the flashplayer executable file to my desktop, from each browser mentioned here, and running it from my desktop. The same problem arises no matter how I try to run the executable file.
My O.S. is Windows XP Professional Service Pack 3, 32-bit (build 2600). I am running the newest versions of Internet Explorer (version 8.00.6001.18702 - the newest version available for Window XP) and Firefox (version 16.0), with all Microsoft updates installed for my PC as of the date of this posting. If you need further info., please be specific. Please note that this same, updated version of flashplayer installed successfully on another desktop PC that is running Windows 7 Home Premium 64-bit O.S., and Internet Explorer 9.
I have always been able to install all updated flashplayer versions - all updated downloads from Adobe in general - without any problems until now. The last version of flashplayer that successfully installed was 11.3.300.271 player and plugin. While going through Adobe's troubleshooting page, as mentioned before, I tried uninstalling version 11.3.300.271, clearing all file caches as instructed, restarting my PC, making sure flashplayer was gone, and then I tried installing the new version 11.4.400.265 again. The same script-bug failure occurred, even with no previous flashplayer version installed at all. So, I went back to the Adobe archives and reinstalled version 11.3.300.271 from before, since it is the newest flashplayer version that will install & run on my PC successfully.
As can be seen from the screen shot, for version 11.4.400.265, as soon as the dark gray Adobe dialogue box opens and begins the installation on my desktop screen, another dialogue box pops open that's entitled "Webpage Error." It delineates a script bug, and asks "Do you want to debug this webpage?" It adds that "This webpage contains errors that might prevent it from displaying or working correctly. If you are not testing this webpage, click no." Below this message are two checkboxes with the options: "Do not show this message again" (unchecked), and "Use the built-in script debugger in Internet Explorer" (automatically pre-checked when this error dialogue box pops up). "Yes" & "No" buttons are provided for the script debugging option. Below that is a white-box window in which there are two lines of cryptic information as follows: "Line: 1"; and beneath that: "Error: Object expected"
If I click on "No" to bypass script debugging, the Webpage Error dialogue box opens again displaying the exact same information, and another webpage opens automatically in my browser from Adobe simply saying Flashplayer has failed to install. If I click the "Yes" button for script debugging, I am taken to lines of data to manipulate that I have no technical expertise to know how to debug at all. As the error box says, "If you are not testing this webpage, click no." I'm not a programmer, or any other kind of computer professional, and so have no expertise in debugging any kind of software at all. The ONLY way I can get these dialogue boxes off my screen at all is restart my PC. They will not delete simply by clicking on the "X" at the top-right corner.
Obviously, there is a script bug in the installation executable file for flashplayer 11.4.400.265 that prevents it from installing on Windows XP computers.
Thank you for any help that can correct this script bug problem, so the installation can go through successfully.
