And uncheck "Enable Enhanced Security."
I'm using 10.1 Pro and was having the exact problem described (first document opened fine, but a second or third would take a good 20-30 seconds to open). After disabling Enhanced Security, I can open 3-4 documents in a row without any slowdown.
It really is a good thing (for Adobe) that Acrobat has no viable competition, because each version has been incrementally worse since version 7.
I'm seeing this issue as well on Acrobat Pro 10.1 but not on 10.0
Have not tested in Reader X
If you have 1 PDF open already from a mapped drive or network share, subsequent PDFs take 15 - 30 seconds to open instead of 2 - 3 seconds in version 10.0
Have not tested opening in the browser yet
This is on Windows XP SP3
I've filed a bug report and hopefully we can get more information.
For the other posters having the problem with Acrobat Pro X, what is your Acrobat version and what is your OS version?
It's the version of Office I was using, I was on 2000, Acrobat X is not compatible with this. It's totally screwed my Printers folder, too. I've upgraded to Office 2010, but I may need to reload XP sp3

I was able to test today with Acrobat Pro 10.1.0 on Win 7 Pro x64.
I am not seeing any slowness when opening subsequent PDF files with 1 already open.
As I posted earlier today, I do see this slowness when using 10.1.0 on XP Pro SP3.
I disabled the "show common tasks in folders" and instead used "windows classic folders" (after disabling the "advanced protection" functions).
I did not notice any changes immediately.
However the program started to work normally after a day or so, and I can't exatly say why.
Probably with the computer restart and internet browser temp files deletion it fixed it.
I then enabled "show common tasks in folders"...and it continues to work normally.
I believe that the "common tasks" thing was addressed in Win7. But it does cause me some conflicts.
I have had exactly the same problem. Since the update, it takes ages to load a PDF through either the standard reader or through Pro X. When it does open, it's open for a few secounds and then hangs. I had no problems prior to this. Using Windows Ultimate, SP1. With 16GB ram & 8 core processors, it doesn't hang for anything. I would love to gripe about the 'attempt' to give me some kind of support by Adobe on this issue but I won't go there.
To fix the load delay.. remove any non functioning or slow Rights Management Servers from Security Settings. Document open triggers UI items to get enabled, which fetches the set of policies that you can apply on a document, and show them within the menu. Somehow this seems to happen each time a document is opened.
How and where did you find anything about disabling enhanced security and how did you find it? in what menu? Is it part of winxp or adobe? Please explain where on earth you found this option - have searched everywhere and cannot find it .
Most certainly NOT . It is most rude for adobe to come up with this and suggest people upgrade or use it when it made it MUCH WORSE and way to slow if it works at all. I wish there was a way to uninstall it and go back to a previous version but guess not. If anyone has discovered a way to uninstall the latest upgrade and go back to previous version PLEASE POST.
I had the same problem -- extremely frustrating -- but I found a solution that works for me.
Open up a pdf file, go to Edit, then click on Preferences in the pull-down. On the left, near the bottom, click on Security, then unclick the box near the top that says "verify signatures when the document is opened". Now all my pdf files open quickly, as they used to! I have no idea what this verify signatures thing is for but I'm ok without it.
Thanks but Actually I had already done that and also unchecked the enable enhanced security. Perhaps it did improve it somewhat but still is slower and more problem to use than prior version(s).Besides being too slow it seems usually to even open a 2nd or higher file when I push enter it does nothing and have to keep on pushing enter till it finally does it or messes up things so much I need to reboot or something - same thing with rt. clicking and going to open with adobe it ignores my command more often than not esp. when have other applications open whereas prior versions did not have this problem.
This is what screws me up. I have to disable this feature of WinXP to keep working when I have multiple PDF files opened.
However sometimes even if the standard "show common tasks in folders" is enabled, it works for a while before it stops working again.
It worked (satisfactorily) before the update.
So, either the update was not applied effectively or Adobe broke it with the new update trying to fix other things.
(anyone have problems with deleting single pages?)
1. Open Folder Ooptions in Control Panel.
- Click START and then click CONTROL PANEL
- Click APPEARANCE AND THEMES and then click FOLDER OPTIONS
2. On the GENERAL tab, under TASKS, click USE WINDOWS CLASSIC FOLDERS

I think different people are experiencing different problems here on this thread but I can at least say from my point of view the issue remains with Pro 10.1.0 on XP SP3 opening the 1st PDF is fine but opening subsequent PDFs is almost always, but not always, preceded with an unusually long delay before they open. I did some brief testing with Pro 10.1.0 on Win7 x64 SP1 and did not reproduce the issue, but at least one other person on this thread says they have had it happen on Win7.
I have tried these things and none of them helped:
- Turned protected mode on. (It was off by default). Turned it back off. No difference either way
- Turned enhanced security off. No difference
(both of these are under edit > preferences > security (enhanced) )
- Uninstalled Adobe Reader. I had Reader 9.4.5 installed as well as Pro 10.1. After uninstalling that, no difference in this behavior.
- Temporarily disabled Symantec Endpoint Protection 11.0.6300.803. No difference in this behavior. Note there is a known bug with Adobe Reader 10 and Symantec Endpoint Protection versions lower than 11.0.6200 - Reader 10 will not run in Protected Mode.
What does help is to roll back to Acrobat Pro 10.0.0 When I do that (which so far I can only get to happen by uninstalling and reinstalling) I have yet to get the slowness to occur with 10.0.0
It seems like everything I do in Acrobat X is really slow compared to 9. I've only had it for about a month, but I'm getting really sick of it. Creating forms is brutal when I have to stare at a loading bar for 5 seconds everytime I drop a new field in there.
Please pleese pleeeze can someone tell me how to remove Acrobat reader X and replace it with
one that works Acrobat 9.
I'm tired of trying all of the helpful suggestions above, none of which have worked, but thanks anyway.
Acrobat, or Reader?
If Acrobat, then you should have the installation file or media. If not, you
will need to contact Adobe.
If Reader, you can download it from here:
I'm not sure if this has anything to do with it but.... having just checked my 'reliability monitor' (via control panel) - there is an warning mark right next to Acrobat X Pro with the message 'Unsuccessfil application reconfiguration'. I haven't asked Acrobat to do anything today so what ever the error is, it's done it off it's own back. (As you'll see from previous notes, i too am having issue's since the update. Using Windows 7 Ultimate SP1)
After all the discussion, I can't resist adding a little dig in the sense that your file are slow to open like the display in this forum. (OK, this goes way back to when the forum was changed over and the analogy is something I just could not resist!) Sorry for wasting space in this topic.
No solution to this problem yet? It's been months!!! Has anybody been in contact with Adobe? We can't be the only people on this earth with this problem!! My hair is getting grayer by each day and my ulcer is growing...
My Acrobat recently got updated to version 10.1.1 and now it opens pdf files without any delay. I would suggest all of you facing this problem to update your Acrobat to latest version (10.1.1) as soon as possible.
Regarding the ridiculously slow opening of PDF's in IE8 web browser (I know not OP's problem), it is still ridiculously slow with Acrobat 10.1.1 and Reader 10.1.1 installed.
If I uninstall Acrobat X and leave Reader (10.1.1) installed they open damn near instantaneously in IE.
Install Acrobat 10.1.0, PDF's can take up to 60 seconds before viewable.
Update to Acrobat 10.1.1, PDF's can take up to 60 seconds before viewable
Turn off all the addins in browser, no change.
Any definite fixes for this anyone .. please? Preferably one I can recommend to external clients as well as they are having the same issue viewing the PDF's off our website.
The problem for me also went away when I updated to v10.1.1. (for WinXP)
The problem is mostly about having thumbnail views applied to your folders and the setting (in XP) "show common operations in the same folder".
If I turned that feature off, the problem went away (with the previous version).
I can still sense some delay in opening of PDFs, with the new version, but nothing like before.
Yeah, I use Chrome myself and the builtin PDF viewer is instantaneous. Can't really tell our clients who work at hospitals etc to change their browser though (IT won't let them), or to turn off "Display in browser" in their Acrobat settings, or to right-click and save as.. to speed things up.
Would be better if Adobe could just tell us where the problem lies or even better .. fix it.
I have not seen anyone post full test results, so here is my testing:
Windows 7 x64
Internet Explorer 8
Adobe Acrobat X Pro
10.0.0 - Works
10.0.1 - Works
10.0.2 - Works
10.0.3 - Works
10.1.0 - Slow to load PDF Forms inside browser
10.1.1 - Slow to load PDF Forms inside browser
I have not found any Adobe Acrobat Preferences that will fix this either.
