Installed update today (01-16-13) Reader v 11.0.01 can not open many previously created pdf files.
PDF files were not created using Adobe.
Can open same PDF files using un-updated versions of Adobe Reader.
What was the purpose of this update that may have caused these problems?
===============================================================
Both version 10 & Version 11 users of Acrobat Reader are experiencing problems (if they installed the latest update) opening many PDF files.
It appears that PDF files that we created using Application: Kofax standard Multi-Page TIFF Storage Filter can not be opened using Adobe Acrobat Reader after the update was installed.
As a work around….
Fortunately, I had a full copy of Acrobat Reader 10 (AdbeRdr1013_en_US.exe) on my computer and was able to uninstall the updated Acrobat Reader 11 and install Acrobat Reader 10 (that didn’t have today’s software update). Prior to installing today's update, we had no problems. After installation of Acrobat Reader 10 (with no updates), we can open PDF files again.
The error message we were receiving suggested that the file may be damaged. However, we were able to open the file after installing a version that did not include today's update.
