ChangeIcon MFC Application has stopped working.

Since the last set up updateson 16/09/2014 for "Update for WIndows 8.1 for x64-based Systems (KB2976719), (KB2989647) and (KB2984006)", I have been getting an error everytime I start up my computer stating that "changeicon MFC application has stopped working". It states the issue as an "app crash" and that the relevant program is "UMonit64.exe".

I traced to program to its directory and ran all my virus/malware/etc scans on it and they all said it was fine. I then attempted to run the program and it came up with the same error that pops up on startup and a second error message saying it wasn't able to run because "ustor.dll" was missing.

I did a system restore to before I did the windows update and sure enough everything worked fine. I then ran the windows update again after restarting to complete the update the "changeicon MFC application has stopped working" error message started popping up again.

So my questions are:

  1. What is UMonit64.exe/ChangeIcon Application?
  2. Did my windows update cause the issue?
  3. How do I stop the error message from popping up everytime I start up?
  4. Do I need UMonit64.exe? I haven't noticed any programs malfunction when I click the "close program" option when the error message pops up.
  5. If I do need it, should I download the missing DLL file to fix it? If so where would be a safe place to download the replacement dll file?
  6. Anything else I need to know to fix the issue or whether future windows updates will fix it for me and I should just ignore it for the time being.

    Hi,

    I have also encountered this error -and I think I know what KB is the real culprit.  After installing 8.1, I decided to install all needed updates one by one, with a reboot in between, whether the system asked for it or not.

    After rebooting from installing KB3045999, I received the error.  I immediately de-installed this KB and the problem has gone.

    Regards

    David

    i too have g750 laptop, i tried all the avail option, and it finally work for me, i think my replies are on the 6th page, but hoped it worked out for u

    i think this was what finally solved it. on my last boot this is what i did.. and i didnt get the error anymore.

    try this FIRST.

    Search your hard drive for a copy of ustor.dll (this is the mass storage device driver for windows)

    Copy this and paste it in to the following folder  c:/windows/syswow64 

    Or you could de-install KBKB3045999.  That caused the error for me, and went away when I removed it.

    I just removed the KB3045999 just to be safe. cuz i also have a program called AVS Video Converter which wont convert my videos if they are over 1.5GB. it used to work, and i think it was related to this issue last time i checked. thanks.

    This worked for me.  Copied ustor.dll from C:\Drivers\Genesys USB Mass Storage Device\common to  C/Windows/Syswow64

    Thanks
