Never hurt to try....
Just make sure you do a clean uninstall for old Adobe Reader before installing the new one. Run Windows updates, clear up any registry and anything in temp folder may help as well.
I'm not sure what you mean by a "clean uninstall". Are you referring to the Windows add/remove process to uninstall software... or is there software I need to download from Adobe, to do a "clean uninstall"?
I have downloaded several uninstall programs from CNET and have used one from IObit, which has a "forced" uninstall feature that cleans up leftover pieces after running a normal add/remove uninstall.
I also have CCleaner, that I use regularly to clean up web and Windows temp files.
I'm not sure what you're referring to when you mentioned the Registry. Do you mean having all traces of my current Adobe Reader removed from the Registry or having all errors cleaned up that might be found by a Registry fix tool?
You're correct. Clean uninstall i referred to meant clean up every single trace of Adobe Reader in your program files, in your registry, in your application data folder, etc. CClearner is a good one. Apart from using it for cleaning up web and windows temp files, did you try to use their Registry fix feature?
What I am trying to say is that you should:
-Clear up any trace left by the program
-Clear up Temp folder
-Run Registry fix
-Restart the computer
-Reinstall the Adobe
That's all i can say. I am not saying that this will work for sure. It is just one of many resolution for you. Good luck!
