Reference Memory Error 0x7c91888f issue

Hi,

I recently installed Microsoft Office 2007 in my desktop, but I did not remove the MS Office 2003 (just for future references).  The installation went well.  Yesterday a pop up message keep appearing on my screen every time I tried to open any MS Office Application. I tried to re-boot the computer a couple of times, but the problem doesn’t seem to go away. 

Because this problem is new to me, and I really don’t know what to do, I just ignored it and clicked the cancel button and continued with my work.

EpfwWindow: ekrn.exe – Application Error

The instruction at "0x7c91888f" referenced memory at '0x03f621b0". The memory could not be "read".

Click on OK to terminate the program

Click on CANCEL to debug the program

As of now, all other functions in my desktop are working properly.  My question is, does this error have any present or future effects on my computer.  I want to prevent any problem in the future as all my documents are saved in my desktop. 

Many thanks.

Hi there,

If you did not realize yet Office 2007 has backward compatibility which means that all the office documents that you created and saved with earlier versions of Microsoft Office, can now be used with your Office 2007. So there is simply no point of why you need to keep office 2003 in the first place since you already have office 2007 installed in your PC. It is always better to keep just ONE version of any Software/Application installed in your PC. Keeping multiple versions of the same thing might cause unprecedented problems.

In regards to the error that is showing up on your screen, your Eset Antivirus / Security Software has more things to do with it than your office 2007. Ekrn.exe refers to your Eset Antivirus / Security Software which might be playing up and not coexisting in harmony with two different versions of office installed in your PC. You can try updating your Eset to the latest version for both the program itself and virus definitions. Alternatively you can try uninstalling Eset and try any of the free antivirus that now provide comprehensive services for home users free of cost.

I have tried many antiviruses in the last few months and to the best of my knowledge and tests that I have carried out, Avast Free Edition and AVG Free are my favorites. Both offer services that are more than enough for home use. For avast you just need to sign up free for every year. For AVG you don’t need to do anything but only install and forget.

For AVG please go to: http://free.avg.com/us-en/free-antivirus-download

For Avast please go to: http://download.cnet.com/Avast-Free-Antivirus-2014/3000-2239_4-10019223.html

I would recommend that you make sure that your windows firewall is turned on when you use these antiviruses.

Hope this information is useful!

Hi,

Some malware might be affected with ekrn.exe. This file located in Windows or Windows/system32 folder. If you are having trouble with uninstalling an Eset Antivirus, please uninstall this antivirus in the safe mode. You can go to the safe mode by pressing F8 key at the windows startup. I give you an application which scan your computer and check for PC issues. You can use this software to solve this problem. Also I recommend installing a security task manager. Using this tool can detect these kinds of errors and help you to protect your computer.
