Okay, finally have installed, but whenever prompted to open 8x version, says encountered a problem and has to close. I can't access it through internet program or stand alone. Have uninstalled and reinstalled a number of times.
You have probably not accepted the License Agreement. Create a new admin user and then launch the Reader under the new account. Accept the License Agreement and then log back into your old account. You then should be able to open Reader successfully.
Uninstall the reader. Go to http://filehippo.com and get older version of Adobe Reader. I used 7.0. It worked well. Somewhere in this forum someone mentioned Windows Uninstall program. It works very well. The site, File Hippo, has a lot of interesting things. Search for Adobe Reader, then on the left side are the older versions. Highlight the one you want. At the top of that column click download this version. This should work. Good luck.
