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:
Then reinstall the version you want of Reader, downloading its full installer from
After downloading, restart your computer and run the installer before doing anything else.
