Adobe Reader DC - Slow Launch

Had this on 2 servers, when I looked in add remove programs one server had 'Adobe Acrobat DC (64-bit)' and users logged into this server had the issue but users on the other server with 'Adobe Acrobat Reader DC' did not have the issue.

For me the resolution was :

uninstall the version that had the issue 'Adobe Acrobat DC (64-bit)

and then rather than downloading the program again from adobe.com as you would normally, google adobe reader offline installer

install the offline version of reader DC - it installs in a different way

So I had this problem with ADOBE DC and it was killing me trying the fixes like enhanced security (checked to OFF) etc.

I saw another fix that said go to the C:/COMPUTERNAME>Programfilesx86>Adobe

This led me to discover that a pprevious version of adobe, Adobe Pro 11.0 still had files in the folder AFTER adobe complete uninstall and clearner programs...

Well i deleted the Adobe Pro 11.0 folder and voila! no more delays in opening PDFs. Which means Adobe DC was referencing the Adobe Pro 11.0 for some process. I am not an expert so i don't know what it was but it was slowing it down. 

Maybe this will help some who have commented that nothign has helped. It has bugged me for 5 months.

Thanks for reporting the issue. In order to investigate the issue further can you pls. provide us with some logs from your system with Enable Protected Mode at startup' and 'Enable Enhanced Security' turned 'ON' in the Preferences.

Following are the steps to generate the procmon logs:

• Download Procmon from https://docs.microsoft.com/en-us/sysinternals/downloads/procmon,
• Launch procmon.exe.
• Set the below filter in procmon ("ProcessName is AcroRd32.exe")

Do the required steps/workflow and save the logs in the end.

Pls. provide the above logs to us using a file sharing utility.

Thanks in advance,

This is an issue with the 3DConnexion API for your 3D mouse.

If you're not using the 3D mouse in Acrobat, you may delete the plugin:

3DxAcr3d.api

Located in:

C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\plug_ins

My organization is also experiencing this issue. I have tried removing Adobe DC, running the cleanup tool, and re-installing. No change. Files from the local PC open quickly, but if its on a network share, they're very slow to open. Its not our network backbone as we have Gigabit and other files such as Word documents open fine. Also, AV has been tested turned off with no change. Only some users experience this issue. I have seen several forms with users experiencing the same issue, so I feel this is an Adobe software issue and not the End Users in the field.

I had the same issue and found on another thread in this forum the following that helped me:

Edit> Preferences > Security (enhanced) and deselect "Enable protected mode at start up" and click OK. (very important to click ok)

I hope this help you as it did help me after a week trying to find out the issue.

Regards.
