Sick of Slow Adobe Reader Startup Times?

This came from FurryGoat who got it from Sanjay’s Coding Tips who found it at Darrell Norton’s blog. It’s a short list of things to do to speed up the launching of Adobe’s Reader – I’m posting them here to remind myself what to change after my next reformat or machine upgrade…

It is all the plug-ins that are enabled by default slowing Acrobat reader down. After removing all but 3, it loads pretty much instantly.

    Here’s how to do it:

  1. Go to C:\Program Files\Adobe\Acrobat 6.0\Reader (replace the C if you installed on another drive, like I did).
  2. Create a new folder called plug_ins_disabled.
  3. Move all files from the plug_ins folder to the plug_ins_disabled folder except EWH32.api, printme.api, and search.api. There should only be these 3 files in the plug_ins folder.
  4. You’re done.
  5. Enjoy.

  1. Randy:

    I was writing a Web Browser App to view several formats and the major complaint was the slow start ups with Acrobat. Everyone here at my little company are grateful. Once Again – Thank you so much.

  2. What a relief! I had built a Web Application that generates many PDF reports, and then Acrobat Reader became so slow (on some machines, not necessarily the old, slow ones). I was afraid I had to rebuilt the report generator …

    By the way, “move all files” means “move all files and folders” (leaving the folders may get you error messages).

  3. WOW fantastic super quick Adobe, thank you. I use a lot of sheet music in pdf and it bored me rigid having to wait so long each time. Brilliant.

  4. This information is very old but I adapted it slightly for the newer version:

    1. go to “C:\Program Files\Adobe\Reader 9.0\Reader”

    2. rename “plug_ins3d” to something else such as “plug_ins3d_disabled”

    now it should start up instantly. the normal plugins in the other folder made zero difference to the startup for me, it was only those 3D ones slowing everything down.

  5. The info is outdated. Here’s a better list of plugins you might want to keep:

    AcroForm/

    AcroForm.api (form fill support)

    EScript.api (form fill support)

    IA32.api (internet access support)

    Search.api (search support)

    Search5.api (search support)

    SendMail.api (internet access support)

    weblink.api (internet access support)

    Also as mentioned above, disable all 3d plugins (plug_ins3d).

  6. Worked great. Thanks!

    Here is some additions to this procedure (that I noticed)…

    – Renamed (added) “_disabled” to the “plug_ins” and “plug_ins3d” folders.

    – Recreated empty folders “plug_ins” and “plug_ins3d” and copied the above-mentioned files to them.

    – Opened Reader directly from its shortcut which kicked off a quick repair install and it replaced the following folders and their contents:

    In …\plug_ins\

    “Annotations”

    “Multimedia”

    “VDKHome”

    In …\plug_ins3d\

    “prc”

    Hope this helps.

  7. I was having issues with version X. Tried removing a few till eventually found the ones that were causing the most problems. THANKS!

    It now loads and doesn’t freeze.

    I agree with Brent. How about a “light install”
