Each time, I uninstalled the version, "re-uninstalled" it using the cleaner and rebooted the computer, but still, none of these 3 older versions worked. I stopped testing after version 9 failed because I concluded that none of the other older versions will work either... Screenshot suggests you are running Windows 10. Adobe Reader 9 and 10 never supported Windows 10 because it didn't exist yet (although they might perhaps work running in compatibility mode for an older OS). As for Adobe Reader XI, the last installer issued by Adobe was 11.0.10, whereas Windows 10 support wasn't added until 11.0.18 (https://www.adobe.com/devnet-docs/acrobatetk/tools/ReleaseNotes/index.html). To install on Windows 10, I would use the 11.0.10 installer and immediately apply the final 11.0.23 patch before attempting to use Reader. Another issue: There used to be an AcroCleaner for Reader 9 at the link provided by Anand in post #2, but it isn't there anymore (and I don't know if it would've worked on Windows 10). In any case, you need to run AcroCleaner for 10.x and later (scroll down at previously mentioned link). Good luck!
