Which windows operating system are you using?

Are you able to roll back, (Restore), to a point before you installed the updates?

This may not fix the problem you were having with updating Adobe, but at least you should get your previous version back and working.

Also, is this a known problem? Try going to Adobe's web site;

http://www.adobe.com/support/products/acrreader.html

and check their FAQ's or Support forums.

Good luck
