Acrobat Reader arrgghhh - SOLVED!

I'm not sure what happen, but my Adobe Acrobat Reader 6.0 has completely stopped working. I've tried uninstalling and reinstalling, and everytime it just crashes, hangs, freezes up on entry. The last thing I remember doing is trying to print a PDF from a scientific journal. What gives? It's driving me mad. For now, I've stopped using it though I still, from time to time, accidentally click on a PDF link, and then BAM, computer seizes up and I have to invoke the Task Bar to kill the offending AcroRd32.exe which continuously consumes something like 40-90% of the CPU. I am not the first to have the problems. A run through the reviews on and zdnet will show you it isn't just me. It's not, really... arrrgghhhh!!!! The most annoying thing is that I really need it to read scientific journals...

Could this be a clue? Go Google! I checked C:\Documents and Settings\torque\Local Settings\Temp, sure enough, Acrxxxx.tmp galore.... ending with AcrFFFF.tmp, each exactly 0 bytes.

C:\Documents and Settings\torque\Local Settings\Temp>erase acr*.tmp
In fact, it worked! So, there's the solution. Thank you

A lot of you wrote to thank me for this post. You are welcome - it was driving me pretty crazy. :) If you want to help the cause, put a link to this post or the blog. Spread the word and stop the madness. Cheers, -T

Phenominal! Solved my problem as well. I'm guessing there were thousands of tmp files because it took almost 5 minutes! I was using a pdf study guide for an exam tomorrow. This saved me! Thanks.

That's right, Phenominal! Solved my problem too. This was just such a pain and you would think Adobe would reference this known issue with. Thanks.

Dude, I searched Yahoo! for:

acroRD32.exe adobe reader freezes and your site came up. You were having the exact same problem I was having. Thanks for showing me how to fix it!

Posted by: Josh at July 25, 2004 1:55 AM

Thank-you, thank-you thank-you! My internal help desk had no clue (and did the uninstall, install). I was about to reimage my hard drive when I found your posting!

Posted by: Allison at August 21, 2004 8:58 AM

Yay! That did it. Thanks much.

Posted by: LLoyd at August 27, 2004 6:55 AM

It works indeed !
P.S. I had to search for acr*.tmp. I found them in quite another directory. But removal of the
two files found did the job.

Posted by: Gene at September 15, 2004 10:58 AM

Thanks for the post. My search on google for acrord32 and cpu found this post and, sure enough, I had 65,535 0-length .tmp files in this directory. Removal worked like a charm.

Posted by: Adrian at September 26, 2004 10:58 AM

Perfect advice. I have experienced the same problem, found this site with GOOGLE and cleaned up the .tmp files as described. Thank you for all of the help..

Posted by: rick at October 26, 2004 12:29 PM

Thanks Dude!!!
I was almost going nuts trying to make the reader work...And thanks to you that its working now...

Thanks again!!!

Posted by: Manish Gupta at November 23, 2004 1:13 PM

awesome, thank u. I also searched and tried a lot of things to fix this including posts from adobe's website. I had the 65,000+ tmp files too and deleted them. This has been a pain in the neck for a few months. Thank u!!!!

Posted by: jda at December 15, 2004 9:11 AM

One more success story - this one problem crippled all of my Adobe apps (Photoshop, Illustrator, After Effects, and Acrobat) and generally gave me hell on earth for a few hours. Adobe's site says to delete your .tmp files, but it doesn't go into detail about the acr0000-acrFFFF.tmp problem. The whole thing is so cause-and-effect that it's surprising that they don't make a bigger deal of it.

Posted by: Carl at December 31, 2004 12:05 PM

Had the same problem. Reinstalled drivers, acrobat reader (a few times!), etc. without success. Vive google! that let me find this page (should have done that few days ago). Thanks to the finder !

Posted by: alain at January 16, 2005 1:12 PM

You're a god! Such a simple fix and yet I found no reference to it on the Adobe web site. I've been tracking this down for days. Thanks for taking the time to publish your findings.

I had 65,535 temp files.

Posted by: Steve at January 22, 2005 4:28 AM

Thanks man! Our IT guys were just about to reinstall my PC. They thought my profile was corrupted... Finally, I can read the PDFs off my work desk. Cheers!

Posted by: Josh at January 25, 2005 7:56 PM

Thanks for the info.... I had 65,634 files slowing me down

Posted by: Jay at February 9, 2005 7:10 AM

Thanks! After numerous reinstalls (and all the reboots that go along with them) and even upgrading to 7.0, nothing was working. Adobe should be shot for this! At first I thought it might have been Firefox's plugin, but IE wouldn't even open pdfs.

I almost gave up on reading pdfs on my XP box... and was about to move them all over to my linux box, right when I came across your site.

Posted by: anonymous at March 8, 2005 10:29 AM

Thanks so much for posting this info. It helped us out too!

Posted by: Donna at March 9, 2005 1:03 PM

OMG!!! THANK YOU SO MUCH! Like everyone else, this was my problem. I tried everything, too, uninstall, delete registry keys, reinstall, blah, blah, blah. Just about to kick my puter off a cliff! Thanks to my Man, Joseph for finding your fix! I agree, Adobe should have referenced this and I even searched their KB for HOURS.

Posted by: Cyndee at March 10, 2005 2:28 PM

Thanks! Yet another user here with 65,535 Acrxxxx.tmp files and all the same symptoms. Deleted them and now everything is fine!

Posted by: JackdawFool at March 17, 2005 4:44 PM

Similar issue here, but it happened about the time I installed Adobe Reader 7.0, and I actually noticed the tmp files first (before any memory or performance problems), because it put them right on my root C directory! But they only gave me about 35,000. I feel so cheated!

Posted by: ~ at March 18, 2005 8:47 AM

This has tormented me for many months. It was THIS POST that steered me in the right direction and solved the problem. says to delete .tmp files in C:\*.tmp. This was clearly wrong.

Even the force didn't help me on this. The dark side is powerful.

May the force be with you,

Posted by: Obiwan Kenobi at March 27, 2005 11:19 AM

Excellent job helping me solve the issue! Acrobate 6.0 Professional just took a dive last night, and stopped working. Your site displayed the fix, and you saved me a headache of trying to get Adobe to actually provide support for their products. Thank you for your help.

Go Google !

Worked like a dream on broken AReader6 APro6 & Apro4

Posted by: Hiper3D at May 5, 2005 10:54 AM

I had this exact same problem. It even gave problems with Word 2000, Adobe Photoshop and CorelDraw. These programs create temporary files in the temp directory. Since this dir was completely filled with acr*.tmp files, the programs fail to create the temporary files.
Thanks for helping out.

Posted by: Gert at May 10, 2005 3:19 AM

Thank you very much for the information you give on your web page and solved my problem.
My curses go to Ad0be for this very very nasty bug and sloppy, disastrous, programming.

Posted by: Roger Schilling at May 25, 2005 2:10 AM

Good call! I had 32,000 of these files in my temp folder. My machine is working way better now. Thanks for the info!

Posted by: Chris at June 9, 2005 6:56 AM

Saved my day!!!

Posted by: Andrew at June 17, 2005 5:10 AM

WoW, It didn't work for me :(

Posted by: john K Gallagher at June 21, 2005 7:17 AM

Thanks for the info Tim!
You saved my day.

I couldn't make Acrobat Reader work no matter what I did: Uninstall, reinstall, install earlier versions etc.

Posted by: Henning at June 29, 2005 3:03 AM

Work's. Thanks Man!

Posted by: Flavio at June 30, 2005 7:04 AM

Unbelievable! I found mine in c:\inst.

Posted by: Susan at June 30, 2005 8:30 AM

Yesssss! Saved my day or two, too. I was about to reformat my C:


Posted by: Pekka at July 3, 2005 9:19 AM

Thanks so much. I had try deinstalling Acrobat, installing a new version of Acrobat Reader (7) and deinstalling twice, nothing worked until I found your page.

I was just about to start looking for xpdf under cygwin to try to work around this.

Apparently this problem has existed for almost a year, spanning Acrobat Reader 6.0 and 7.0. What gives?

Posted by: Randy at July 16, 2005 8:30 AM

Thanks for saving me another one zillion (re)installs of Acrobat Reader. Somehow each install used to work once (and just once) for me !

And yet another person helped by this info. Thanks a ton, and screw you Adobe! 6.0 Was such an utter piece of garbage!!!

Posted by: mike at August 2, 2005 10:30 AM

un-fre@king-believable!!!!! I have know idea how long I've been dealin with this issue. Now I wonder if about 100% of my co-workers are experiencing it as well.

Dude, you rock!!!!!


Posted by: junyoure at August 6, 2005 4:37 PM

So how did all those files get out there, anyway ???? Will we have to do this every xx months ?? I had over 65,000 of them - enough to choke a horse ( er, I mean a pc ). THANKS !!

Posted by: Joe at August 10, 2005 10:59 AM

Another satisfied customer. You, sir, are a STAR!

Posted by: Tony at September 15, 2005 4:10 AM

Saved my veggie bacon, too. 65,536 temp files. After 20 minutes, it's still deleting. My guess is, there is some Windows cap at 2 to the 16th power (65536) files. 16-bit file system. Acrobat just freezes because it can't create the 65537th temp file. Any ideas as to why Adobe doesn't clean up their temp space? Any ideas as to why Windows doesn't clean out temp space upon reboot?

Posted by: Dan at September 27, 2005 2:48 PM

Have you ever used Acrobat 65537 times?

At the moment I am not running neither Reader nor Acrobat, but from time to time a new Acr*.tmp file appears in C:\windows/tmp directory! Each is about 8 Mb. Today afternoon they appeared at 15:46, 15:56, 15:59, 16:04 etc. Although I have deleted previous ones, numbering did not start with 01, but with C3.
As deduced from their number when I noticed the problem, it had started just few days ago. (My C disk is rather small.)

I have tried adaware and Sophos antivirus - nothing strange appeared. (I suspected that they were not produced by Reader.)

Opening and closing Reader did not remove them - Adobe claims that it should delete files with this name.

Posted by: Damir at November 10, 2005 8:04 AM

Damir: Open a PDF in Acrobat 6.1 creates 4 different Acr*.tmp files. Who knows how many are created during normal use. So I doubt you have to run Acrobat sixty five thousand times to see this problem.

A pox on Adobe for releasing software any software engineer should be ashamed of.

Tim, you made my day after a terribly frustrating day of un/re-installing poorly designed Adobe software. Thanks so much!

Posted by: Mike at January 10, 2006 1:22 PM

Unbelievable! Two YEARS later and it is still happening? My wife's machine was locking up ACRORD32 every time she browsed into a PDF file. 65,535 files later, and it works now!

Posted by: ldeffenb at January 11, 2006 10:15 PM

I don't have those files in my temp file, yet my adobe still doesn't work :-(

Posted by: Billy at February 26, 2006 2:56 PM

Another happy System Engineer :-)
Thanks a lot.
