Stop 0x0000007E

Help, I have been trying to update my device software from 4.3 to 4.5, using Vista SP1 but am plagued with "Stop 0x0000007E"


I've updated my desktop manager to 5.0, but this has not helped.  The problem occurs during the install of the firmware update and also when disconnecting my device from the USB port.


Please advise.

Re: Stop 0x0000007E

Hi and Welcome to the Forums!


There are a couple of hits in the KB's with that error code...see if they are helpful:

  • KB03280 Mail system interface library could not be loaded 0x0000007e
    KB11410 Desktop Manager: DesktopMgr.exe - Unable To Locate Component


Otherwise, I'd recommend the following sequence:


1) A clean uninstall of DTM:

  • KB02206 How to perform a clean uninstall of BlackBerry Desktop Software
  • Reboot the PC after the uninstall sequence is completed


2) A fresh download and install of the appropriately compatible (with your PIM) DTM software:


3)  A fresh download and install (to your PC, atop DTM) of the appropriate OS package from your carrier:


4) Retry the OS update


Good luck and let us know!

Well the problem ended up being a Vista problem.  There a couple recent updates that had to be removed.  This fixed the problem.  Thank you Dell support.
