Slow to open second PDF file with Reader X

I am in the camp where disabling "Enable Protected Mode at Startup" did not work alone.

First, I uninstalled, rebooted, and reinstalled a fresh version..ended up being 10.1.0.

Then I disabled "Enable Protected Mode at Startup" but it did not have any effect.

Leaving "Enable Protected Mode at Startup" disabled, I went on.

I opened Reader by itself without a document, went to HELP, and "Repair Adobe Reader Installation."

Mid process, I had to close adobe reader leaving the repair process to continue.

That worked.

My second PDF opens normally now.

I experienced the same issue with Adobe Reader 10.1.0.534 (the full version number that appears in the About box) on Windows XP Professional SP3.  I describe the issue as follows:

* After one PDF file is opened, the second, third, fourth (and so on) files are slow to open, maybe 5 to 10 seconds per file, when opening by double-clicking on each file in a Windows Explorer folder.

* The problem (with files opening slowly) does NOT occur when dragging the files from the Windows Explorer folder to the Adobe Reader icon.  The problem does NOT occur when opening files from the Adobe Reader "File: Open ..." dialog.

* The problem does NOT occur for other application programs, such as Microsoft Office, IrfanView.

* The problem is associated with "Enable Protected Mode at startup" setting in File: Preferences: General.  Turning off "Enable Protected Mode at startup", and then re-starting Adobe Reader, is a solution or at least work-around (files open quickly, but on the other hand a security setting is disabled).

Try turning off your virus and malware protection and try again. See if it speeds up.

We hare having the same issues here at work and my co-worker discovered the problem and solution.  He discovered that if you "Uncheck Enable Protected Mode", this will speed things up again, but not sure if you want to turn off a security feature.

If you open Adobe Reader X first and open files through the application, there are no issues.  This appears to only happen  if you click on the PDF file, then click on the second PDF file to open it.  It seems to hang for about 30 seconds or so.

Not sure if it's really a solution though, but just go into the Adobe Options and "UNCHECK" Enable Protect Mode" and you'll notice it will launch the second PDF faster.

HTH

I too was having a similar problem.  Taking 15-30 seconds for adobe reader 9.4.4 to launch after clicking on a pdf file attachment in emails or opening PDF files from web sites.  Seem to start right after adobe did an automatic upgrade.  However, the problem seems to have been resolved when I opened adobe first without a document, clicked on "Help", then "Repair Adober Reader Installation".  Maybe this will work for you too.

Same here.

HP Computer, XP SP3, with ATi HD 2400 card.

Recently updated Acrobat and ATI drivers, not sure if related.

Same problem here: Win7 x64, Intel i7-860@3.2 Ghz, 8Go RAM!

A real pain in the b..t.

Hello,

I also have the same problem (my computer has Windows XP sp3 and Adobe Reader X).
I can not see the explanation for this and I can´t fix it.
But... if we drag the icon of 2º file (and 3º and etc.) to the program window it opens quickly!!!
