if i run the file isolated and it works. When i run the same file through the QMC, the error occurs.

It happened after the Windows Registration

Hi,

So if you run the reload (i guess it´s a reload task) with QlikView Desktop it works?

What version are you on?

What was the Windows update that was installed?

Is it only basic reload tasks or do they contain a distribution part as well?

Hello Danilo,

Can you resave the (hit apply) the task?

If that does not work, can you remove it and add it again?

Regards,

Erik

Hi!

Same Error here!

QV11.20SR6

No Publisher License

Win2012

Document log does not exists, as the error is thrown after 1 second!

It seems like it happens before Distribution Service starts the qvb.exe

It does not happen all the time; most time the task runs fine, sometimes it throws the error below; So it should have nothing to do with the filename!

What's the name of your task?
