Issue with using AcroPDF viewer - Blinking Cursor - High CPU Usage

Hi,

I have a VB6 app that uses the AcroPDF.dll to view PDF files.

Since the update to 15.23.20053 anytime I use the AcroPDF control to view the PDF I get a constantly blinking cursor, it flickers between the arrow cursor and the loading cursor. Also the CPU usage jumps up and slows down the PC.

In the background I can see a process called RDRCEF.exe constantly opening and crashing... I think this is the issue.

Would anyone have any ideas on how to resolve this issue.

As I said this issue only occurs with the update to 15.23.20053.

Specific details:

AcroPDF.dll - version 15.23.20053

RDRCEF.exe - version 15.23.20053

Thanks.

Hi,

Thanks for the reply.

It's a standalone VB application (Windows Form based Application). It has no integration with IE.

Thanks,

Hi pf36742715,

Could you please try disabling Protected Mode and see if that helps:

Launch Reader>click Edit>Preferences>Security(Enhanced)>uncheck the box Enable Protected Mode at startup>OK.

Also, try to update Reader to the latest, launch Reader>click Help>select Check for Updates.

In addition to that, you may try creating a new user account and see that works, visit the following link which explains how to create a new user account in Windows: https://support.microsoft.com/en-in/help/13951/windows-create-user-account

Thank You,

Shivam

Hi,

Thanks for the reply.

Disabling the Protection Mode does not a difference. The issue is still there.

I've updated the version of the Reader to 2015.023.20056 and it does not a difference. The issue is still there.

This issue is affecting multiple PC installations (20+) so creating a new user is not a viable option - I haven't and will not be trying this approach.

Thanks.
