System Access Violation Error:

C_Hayes · November 30, 2014, 6:40pm

I have recently experienced a recurring problem with eM Client. When opening or using my email, I often get a System Access Violation Error: Attemped to read & Write protected memory. eM Client will then close and scan itself before it can be reopened. Is there a permanent fix for this?

Paul_Technical_Suppo · December 1, 2014, 9:33am

Hi, are you able to open the application at all? What version of eM client are you currently using on your computer, can you check for the exact version number in Help > About?
What mail service are you using with eM client?

Is there an error report window displayed after this issue occurs? If so, can you please click on the “Show error” button and post the content of the error here on the forum?

Thank you,
Paul.

C_Hayes · December 1, 2014, 6:02pm

Yes, I can open the application. I am using Version 6. I am using att.net mail (run by Yahoo, I think) with eM client.

The error window pops us randomly when I am going through opening, closing, emails. The first lines of the Error Message read:

Windows NT 6.1 System Access Violation Exception. Attempted to read and write protected memory. This is often an indication that other memory is corrupt…

The messages goes on from there. I hit OK in the box and eM Client closes and then scans itself. Then I am able to reopen it.

Paul_Technical_Suppo · December 2, 2014, 11:30am

Hi again, please submit the whole error shown after the crash occurs, or at least first 10-15 lines.
Also please check for the exact version number as I previously suggested.

Thank you,
Paul.

Hi again, please as suggested under another topic, please try to update eM Client to the most recent release and run the referenced tool, check if the issue persists.

Thank you,
Paul.

C_Hayes · December 2, 2014, 11:25pm

I redownloaded the eM Client install program. A repair error box appeared and the program went through a repair process before finishing the install.

The issue still persists

Paul_Technical_Suppo · December 3, 2014, 12:40pm

Hi again, unfortunately this might be an issue connected to some other system faulty or another application that tries to access the application’s data.
When the error occurs, can you please open task manager from the “Run” tool using this command:

%SystemRoot%\SysWOW64\TaskMgr.exe

And when the error occurs, right click the “MailClient.exe” item and select “Create Dump”, this will generate a file on your computer containing data about the application’s behavior etc., however this file may be too large for sending it over email, can you please use some of the common file sharing services such as dropbox/google drive or wetransfer to submit the file to my email mcgregor@emclient. Also please include a reference link to this forum topic.

Thank you,
Paul.
