What version of Adobe Reader?
We recently rolled out Acrobat Reader Vers. 10.1.3(Previously 9.5) and are experiencing now the same Issues.
What we already found out and tried :
This appears not only if the 'CR' is in the document name but also if it is anywere in the Filepath eg. "C:\Documents and Settings\CR\123.pdf"
Because of Concern spezifications we cannot enable the "Protected Mode on Startup"
and adding the registry-key(description from http://patrickhoban.wordpress.com/2011/07/09/124/) didn't solved the problem.
The real problem now is, that we got many auto-generated contents that sometimes create files or paths that contain those two letters,
so we really hope there is a acceptable Solution for this.
I was having the same issue. Apparently it is related to your browser settings and is applicable to both the Reader and the full Acrobat version. Once I applied the instructions, it worked like a charm.
