I wanted to deinstall Adobe 8 reader but failed because Windows installer demanded " AdobeRdr812_de_DE.msi" file wich cannot be found. I installed already Adobe X reader. What to do?
I would suggest that you try removing all traces of any versions of Reader using the Acrobat and Reader Cleanup Tool:
http://labs.adobe.com/downloads/acrobatcleaner.html
Then reinstall the version you want of Reader, downloading its full installer from
http://get.adobe.com/reader/enterprise/
After downloading, restart your computer and run the installer before doing anything else.
