I've now done some testing on a windows 7 machine.
I tried several versions ov Adobe Reader and saw there were specific versions that failed:
- Adobe Reader 9.5.0 works
- Adobe Reader 9.5.4 works
- Adobe Reader 10.1.0 works
- Adobe Reader 10.1.1 works
- Adobe Reader 10.1.2 does not work
- Adobe Reader 10.1.4 does not work
- Adobe Reader 10.1.6 does not work
- Adobe Reader 11.0.0 works
- Adobe Reader 11.0.2 works
Interestingly the error started occurring at the same time Adobe Reader started giving the opportunity to check out and open documents from SharePoint in the client application. This I will leave for any Adobe support representatives to respond to if they want, but for me, the solution was to downgrade/upgrade my Adobe Reader X.
Let me know if this works for anybody else!
