adobe reader X very slow to open some PDF under windows 7 64-bit

It takes 2 minutes to open a one-page PDF. When double clicking on the PDF, Adobe reader opens but the PDF content doesn't display. It says 'Not responding' for about 2 minutes before it can display the content of the PDF. The PDF is just a one page file. It can be opened by other versions of adobe reader instantly. It can also be opened instantly on another PC which is also W7 64 and Adobe reader X.
WHat can be the possible conflict between reader and my W7?

Try a program called nitroPDF. If that is slow too, then it is PDF's. If it is fast, then it is adobe, and I would recommend uninstalling/reinstalling.

What is your computer's specs? That might also be an indicator so as to why that application responds too slow for you. .

Might want to peek at Foxit Reader. Not as much baggage as Adobe Reader. IMO

Adobe Reader X is not for Win 7 - 64-bit

I had the same trouble with Adobe Reader X running on Win-7 64-bit. Note all of the bad reviews for this combination: Adobe Reader X - Free software downloads and software reviews - CNET Download.com

I uninstalled Adobe Reader X and re-installed Adobe Reader 9.4, everything is fine now.

Yeah olive I'm on Windows 7x64 too and it IS slow. A one page text pdf takes ten seconds to open instead of one. After some playing around I discovered that it's slow at first. Once you open a few pdf files a few times everything becomes normal like Adobe Reader 9.

Kinda annoying, I do think that adobe took a step backwards with reader X. The buttons now look very sub par as far a graphics go. Hope something gets done about this when 10.1 comes out, I dislike using other pdf readers.

Same thing here. I have a Compaq 8510p with 4gb RAM and a SSD hard drive, running windows 7 x64. Adobe Reader X is SO slow opening up .PDF files that I went back to Adobe Reader 9. What's interesting is that I have Adobe Reader X on a Dell Latitude D630 with only 1gb RAM and a 7200 rpm HDD, running Windows XP, and it opens .PDF files just fine.

Just Report,in Adobe Acrobat X Pro,opening a document is very fast,
almost take you 1-2 seconds to open a thousand pages documents,
but when using Reader X,is significantly slower than the Acrobat.

quick fix

Go to Edit / preferences / general - the uncheck box "Enable protected mode at startup" This got rid of the lag in opening adobe docs.

You know? Drop that thing, is bloated as hell... better use FoxIt Reader, it is lightweight and has better security tools than adobe reader...

See ya!!!

I realize this is an old thread, but it came up high on the search, so I thought I'd contribute a solution.
I was having this problem very recently in Reader 10.1.8 and found that simply closing the Tools Pane sped it up immensely!
Hope this helps.

I think you are all missing it

I bet Acro X Std (what I'm using) is "phoning home" every time it's opened, for the first time, during a login session. After I load the program the first time, I can quit and then re-launch and it opens back up fairly quickly. But that initial load, that's a pain. The app just sits there, either phoning home or loading some extraneous s__t. This lag happens even if you just launch the program without trying to open anything on my Win7 X64 Ent WS.

Of course I use Foxit, but Foxit can't edit and crop and secure the way a paid version of Acro does, so sometimes I am forced to launch it.

I could be wrong, but anyway, the control panel doesn't look the same as the advice given here so I'm posting a few shots of Acro X standard. I unchecked a few things,

*Use only certified plugins
*Allow opening of non-PDF extensions
*OF COURSE updater is turned off


but don't have the time right now to log off and back on to actually see if it made a difference. I see it says it's already in certified mode. I'll work on it a little more and see.

I am using Windows 8.1 but have the same issue with Adobe Reader XL.
I found the post that said to UNCHECK the Enable Protected Mode Check Box.
This Worked. Adobe Reader XL open quickly and the tools actually load quickly also!

The setting is now under the Security (Enhanced) Selection. Just uncheck the Protected mode and that will fix the SLOW ISSUE!

Thank you Spengler for the tip!
