AcroRd32.exe Prevent Acrobat Reader from staying open

When you visit a website that links to a pdf, then close the pdf file, the AcroRd32.exe will not close, it will sit open, using your resources and memory on your PC until you restart.

This simple fix will disable that function of Acrobat reader and take back the memory.

1) Open Acrobat Reader
2) Choose “Edit”, then “Preferences”

pdf edit preferences

3) Click on “Internet”, then uncheck “Display PDF in browser”.
pdf display in browser
4) Hit OK

Now AcroRd32.exe will close when you close the reader, not stay open forever!

    hmmm… I’m having a similar problem. :(
    I can’t do these steps because Adobe Reader closes right after clicking preferences. T_T

      Breisa,

      You might have a problem with the Reader software, I would try to download the latest version, then try the steps again and see if that helps.

        I had the same problem; Acrobat Reader would close immediately, not allowing me to apply the “fix.”
        I had to uninstall the program, reinstall, then apply the fix.
        BTW, reinstalling the program didn’t solve the problem; it only allowed me more time to apply the “fix” discussed here.
        Thank you.

    I cannot open some attachments because of an internal error and then a message Instruction at “0x00B5ae65 referenced memory at 0×00000038″. What is going on?

  4. Great stuff. I’m killing a lot of processes now to speed up my PC, finally! Thanks!

  6. Rick says:

    The box was NOT checked when I opened as you suggested, yet AcroRd32.exe is still using 40+ MB of memory! What’s with this?

    I did as you suggested, now instead of AcroRd32.exe using 50% of cpu’s, I have two instances of AcroRd32 taking up 100% of cpu’s. Had to kill both in Task Manager to regain use of computer.

  12. JT says:

    Thank you. This clear solution is very effective and helful.

  13. Lucy says:

    Glad I found this – thought I had a virus!
    I had 2 instances of acrord32.exe – one using 99% of cpu
    Hate acrobat – hate the constant do you want to update nonsense…
    Have to have it because the HMRC use it and nitropdf doesn’t display all their forms correctly
