Problem in Reload Task...

Mon, 26 Jan 2026 18:19:17 GMT

After installing a QVS9 SR1 version, i've got a problem with the reload feature :

When i try to reload a document regularly, i've got this message in the log :

Failed to create QlikView Enfine.. Exception=System.UnauthorizedAccessException

Anybody to help me ?

Any details? What is regularly? Continously? Is it only happening with one special document or also with others? Is the reload really not working or Is there only the error message in the log? Are there other errors in other logs (eventlogs etc)? Have you checked permissions? Are you using DMS or NTFS? Is the file thet ought to be reloaded in use? Have you tried to copy the application (probably to another location) and reload the copy? Have you tried to change the reload interval?
I assume you have already restarted the machine and the problem persists.

Hi Joachim,

I give some more details : This a completely new install, and the problem happends on any automatic reload scheduled. Below is the exact error message (partially English/French) that i have :

An instance of the QlikView Engine is being created (attempt 3/6)
Starting QlikView Engine
Failed to create QlikView Engine.. Exception=System.UnauthorizedAccessException: La récupération de la fabrique de classe COM pour le composant avec le CLSID {28CB32FB-415E-11D1-934D-0040333C91CC} a échoué en raison de l'erreur suivante : 80070005.
à QVBWrapper.Document.CreateQVBProcess(ILogBucket i_LogBucket)

Permissions : which ones ?

File : not in use

Restart the machine : yes, but same problem...

Regards,

Eric.

OK, that seems to be a good trace. Might be there are permission problems on the QVB (QlikView-Batch DCOM). Check with dcomcnfg on your server (Component Services => My Computer => DCOM Config => QlikViewBatch 7.0 Application). I suppose the reason of your error must be there, under "Location" or in the "Security" settings.

I have found this, but what is the user or the values to configure ?

First, in "Location" "Run on the local computer" should be activated (which most likely IS, I assume).

At least the user under which the QlikView distribution service is running should of course be granted the launch and access permissions ..

These parameters are correct, another idea ?

Well, in my opinion it has in some way to do with the QVB-DCOM anyhow. But when you say it's correct, then I'm out of ideas. Perhaps you could try to locate qvb.exe and run it to register it again. Perhaps you could also try to check which processes under which users are accessing which files with which success with Sysinternals (procmon, filemon etc..).. Or just give it to the support, they can check your machine directly.. Sorry, no more ideas ..

I've had the same problem, i've re-run qvb.exe and currently doing some testing.
