The option to combine PDFs by right clicking on the files does not appear on my machine. I've read the fourms and tried the following:
1. All adobe products updated
2. uninstalled/reinstalled Acrobat Pro
3. repaired installation of Acrobat Pro
3. followed another forums suggestion of running: regsvr32 "C:\Program Files (x86)\Adobe\Acrobat 10.0\Acrobat Elements\ContextMenu64.dll". problem persisted. I got error message 0x80070005.
I have 100s of PDFs to combine! Thanks in advance for any suggestions!
(Win7, x64).
