Sorry for the delay, I thought someone answered your question. The first possibility is that you're clicking on a shortcut pointing to a bad location. So right-click on the icon, and if in Windows 7, click on 'File Location', and if it tells you there's no file, that's the problem. If it goes to a file folder, see if an 'exe' file is in the folder. It should say something like 'AcroRead.exe' but I forget the names they use now. Click on that, and see if you get the same error.
If so, you got a bad installation, or the program is left from a prior uninstall, and didn't finish. So now, at the search bar, type 'Uninstall' and search for 'Adobe Reader' in the list. Uninstall it. If it does NOT appear in the list, it means a previous uninstall didn't go well, and that's why you're getting the error. You might have to search for 'Adobe' in all your directories and wipe out any 'Acro' files you find. That takes hours.
So instead, download and install the latest Reader without previous uninstall; it might clean up the prior uninstall for you. For installation of the new one, don't accept the default directory name presented. Give it a new name (even just add a letter) -- lest the new program access the old leftover files (if any).
If you get the same error message after installation, you'll have to uninstall Reader again and maybe all the old locations will be wiped as well. Then, reinstall again. If not all wiped, then you'll have to do the hunt for all 'Adobe' folders, but bear in mind Flash stores in those folders too, so don't delete the Flash files.
This kind of thing happens often. Reader is a buggy product, because it's free. Good news is, the next time that same error occurs, you'll know what to do.
I ended up getting Adobe Acrobat 9 (later versions are less compatible with the programs I use), and it can do OCR recognition (turning all those Google docs from the 1800s and early 1900s into searchable pdfs, and all its Gibbon or Shakespeare, too). But Acrobat 9 might cost $100 (at Amazon, but here at Ebay it's cheaper). It freely updates, though. Some folks have hissy fits about it being an older version, but for Government work I need it and it performs well.
