Do you know what causes the fault?

EMC Support is still looking for the Root cause of this.
What is going on is one of the task gets corrupt and it is preventing Xtract from loading.

Not all the task are bad. if you don't want to recreate all the task you can start by removing them one by one until you find the one that is corupted. Then put the others back.

To help you for the future (until this gets fixed) I would export all your tasks from the registry (when it's working) and keep them aside. If the problem surfaces, import the registry.

In anycase, open a support incident and have them put you on the affected customer list of the "bug" that was opened for this.

Hi,

I have a customer with excatly teh same problem running ob 4.70.434.

The registry key that has been referred here does not appear to exist - please advice

I experienced the same problem. The path was different in my case as well, but the end result was that it resolved my issue. Try this path:

HKLM-SOFTWARE-OTG-EmailXtender-EmailXtract_Exchange-Tasks

I would definitely export the key before deleting anything. Then delete any tasks that you have created until you remove the corruption and can open the application GUI. I would then create a .REG file so you can restore the key to a working state easily in the event it should corrupt again.

Hi,

I experienced this same problem almost 12 months ago - and now I'm implementing EmailXtender v4.70.477 at another customer site and guss what - it's still happening!!!

The issue has nothing whatsoever to do with so called "corrupted" tasks. The issue is this:-
1) Create a recurring task in EmailXtract and configure it to "run as a service".
2) You can exit out and relaunch EmailXtract without a problem as often as you like - UNTIL THE STROKE OF MIDNIGHT. Try launching the EmailXtract GUI at 12.05am the day after the task was created and the GUI will fail with the error message popping up in the Application Evant log!
3) Edit the registry and delete the task. No need to bounce the EmailXtender services.
4) Presto - the EmailXtract GUI works again!

This is a very very serious issue/bug, as my customer needs to schedule recurring archive and shortcut tasks.

I have to agree with you. I still haven't found a resolution.

What operating system are you using?

Could Data Execution Protection be the culprit? We recently solved an issue with exQuery constantly blowing. We turned DEP off by changing the boot.ini entry '/noexecute={optin|optout}' to '/noexecute=AlwaysOff'

I think I might have solved it! If I create my EmailXtract tasks via the actual console of the EX server rather then via a remote desktop session, the EmailXtract GUI doesn't seem to crash anymore. For some reason, it doesn't like the recuurring tasks being configured via remote desktop.

My understanding is that Extract is not a multi threaded application. Therefore you should always be on console 0 when administering the EX server.

To do this correctly, enter the following steps:

Start > Run > mstsc /v:machinename /console

The above will force Console 0.
