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!!!
Same problem here: Win7 x64, Intel email@example.com Ghz, 8Go RAM!
A real pain in the b..t.
HP Computer, XP SP3, with ATi HD 2400 card.
Recently updated Acrobat and ATI drivers, not sure if related.
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.
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.
Clicking on "Help", then "Repair Adober Reader Installation" worked for me too.
Try turning off your virus and malware protection and try again. See if it speeds up.
Yes, but there is nothing to repair, this is a fresh install on version 10.0.1.
Well, mine was a fresh install as well, and I did the repair, it repaired and it works fine now
Repair did not work.
Disabling protected mode as someone said before did work.
Yes, I've discovered that it doesn't work. It worked only until I restarted the computer the
next day and then it caused other errors. I'll try disabling the protected mode tomorrow when
I'm back at work. Thanks,
Thanks for verifying disabling "protect mode" worked for you. I"m not sure how to contact Adobe to let them know about this issue. I'm aware they may have a security patch update on June 14th, 2011. But it does not say if it addresses this issue or not.
I'm packaging this software for our enterprise environment and I had to find the key because this might be an option we have to turn back on later. The key is located in \\HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\10.0\Privileged
Name of the key is"bProtectedMode"
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).
Since disabling the protected mode I haven't had any issues anymore. I wonder what the
security setting does and how important it is to have this enabled? Let's hope the problem
will be fixed with next updates.
Windows XP SP3 here, the very same version of Reader X (10.1.0.534) fresh install and protected mode DISABLED but the problem still exists.
Steps to reproduce the issue:
1. open a folder with a number of PDF files inside
2. double click on one of them: it opens in one second
3. double click on another one: it opens after 10/15 seconds
I think the problem is a sort of pre-rendering that Reader does on the selected PDF when you open them from File Explorer.
This is what's happening:
1. open task manager, Process pane.
2. open the folder with a number of PDF files inside
3. double click on one of them: it opens in one second and an AcroRd32.exe process starts. Leave the document open.
4. SELECT (not double click) another file: the task manager shows TWO additional AcroRd32.exe starting
5. when they close, double click the selected file and it opens instantly
6. SELECT another file: again, two additional AcroRd32.exe processes start. If you immediately double click the same file, it takes 10-15 seconds to open and this happens exactly when the two additional AcroRd32.exe processes stop.
7. double click another file: again, two additional processes start, the file opens exactly when the two processes close.
If you have the same files on your desktop, not in a folder, the files open instantly also ten together at the same time.
Windows Explorer in Windows XP uses the "Common Tasks" view for folders by default. The common tasks view displays commonly used options, links to other folder such as the desktop and details about the currently selected file in the left pane of a folder's window.I figured out that the "Common Tasks" view is causing the delay in opening PDF files with Reader X from the Windows Explorer. The workaround is to set the Classic view in Windows Explorer, then you do not have the delay anymore.
While testing on several XP-machines the following setting must also be unchecked:

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.
My second PDF opens normally now.
I see what you mean about changing the folder view to classic. That works
like a charm for me. Any idea why this is happening? Sounds like a bug to me.
Disabling protected mode at startup worked for me, too - on Windows 7 Professional
