I found that Real Player (current version as of August 2011) was causing the crash and DEP error…
I removed it and everything seems to be working fine now…

I restarted, I did everything. I can’t find which executable file is causing the crash, (I am trying to print coupons off of a coupon site.) I can’t figure out what to do.

Thank you very much! The second method worked perfectly for me. Before, I didn’t have any problems with Firefox, but after installing I think version 3.0.8, it started to give random crashes because of a BEX error from DEP. The first method doesn’t work for me because it says that Firefox requires that DEP is on, so I did the second method instead. Thanks again!

Oh, and you may want to note that you have to restart your computer for the second method to work.

Hi, I tried your methods to delete DEP because it keeps shutting down internet explorer on me and it is causing alot of problems, but when I type the command in the com. prompt screen it says that “the data is not valid as specified”. What am I doing wrong? Please advise asap.

Thank you,
christine

Try to disable DEP using the first method and then later turn it off completely with command prompt if it still doesn’t fix your Firefox problem.

And for the problem of bcdedit command being invalid, make sure you are running the Command Prompt in Admin mode and also make sure you have entered the complete code correctly.

A Firefox support responder told me to try this page to fix Firefox’s constant crashing. My Command Prompt (running Vista) says “bcdedit” is not a valid command, or something. ????
