Adobe Reader 10.1.3 Performance Problems (Open PDF from Outlook)

Hello all,

Adobe Reader 10.1.3 Multi Language version was rolled out to several hundreds of Win XP SP3 client machines.

Now users start reporting that Adobe Reader starts very slow. Most users complain that opening a PDF attached to an email in MS Outlook takes very long (10 sek up to several minutes).

In some forums I found problems with PDFs in Outlook in versions before 10.1.1.

Does anyone has an idea what causes this slow response?

Is there anything we can test to come closer to the problem?

Thanks for help.
