Qlik Sense - An error occurred App is already open

Anonymous — Tue, 14 Oct 2014 18:32:18 GMT

Hi,

I installed The Qlik Sense desktop client. I'm trying to create some sheets, but i'm getting almost in every click the message:

An error occurred

App is already open

(see also attachment)

And i can't save or create anything.

Any advice?

Thanks

Jim

Its a message reporting that Qlik Sense Desktop cannot open another app in the session you are using. Please verify that you only connect with a valid client. If that failes restart the program and all sessions will end.

If closing Qlik Sense Desktop doesn't work. Go into Task Manager (ctrl-shift-esc) and end all the processes related to Qlik Sense (QlikSense.exe and QlikSenseBrowser.exe)

Hi Johan,

What do you mean by "valid client" ? I downloaded the desktop client and tried to create some graphs. But even if i'll restart the program, i keep getting the same message.

Thanks

Jim,

Have you tried reboot the machine, then like Josh Good explain when you launch Qlik Sense .exe file make sure that you just see one Qliksense.exe and two Qliksensebrowser.exe within task manager.

Jim,

Does it happen randomly when you are working with any qvf? Can you replicate the same issue when you open our sample QVFs? is there anything specific that you notice when the error show up?

That's a good catch. When i'm working on yours QVFs, it happened just once. When i'm working on my QVFs it happens continuesly. Actually, it doesn't seem to be any pattern of when it happens. The only thing is that it happens only in edit mode.

Thanks

Yes Gio,

my QVFs are there and it is not a shared or roaming profile. My QVDs are in another location. Does it matters?

Jim,

That should be fine, can you please provide the logs most resent one when you encounter the issue? C:\Users\<user>\Documents\Qlik\Sense\Log

thanks,

Gio

Jim,

how many times do you see this error? from the logs I just see that you encounter like once the error out of 10 times that you open the document? for any change are you using Qlik Cloud?

I see this error when i'm trying to create something on edit mode and i get it almost in every click. On the log that i sent you, i just went inside and simulated the issue. I'm not getting this error in view mode.

Regarding the Qlik Cloud that you mentioned, i don't know where is it. Can you help?

Thanks

Jim

The only thing I can think of is something is holding either the .exe or QVF files. For any chance do you have an antivirus running on your machine? if you do, can you disable it and try again? For any chance do you have any other machine that you can install sense, so we can narrow down to a particular machine.

Hi all -

Jim and I looked in to this issue a bit further and found that removing our QVD layer removed this issue.

So our before scenario is as follows:

We have a Qlik Sense app that loads data from a database source and stores that information in to 4 QVDs. We have a second Qlik Sense app that loads data from those 4 QVDS. ONLY in edit mode of the second application did we see the errors with no predictability as to when it would occur.

Here is out scenario afterwards that appears to eliminate these errors:

We have a Qlik Sense app that loads data from a database source into an application. While in this same application we can view or edit with no issues.

Does anyone have insight into why the QVD layer might cause the issue? (And please refer to the attached logs for potentially useful information)

Cheers!

Eric

It looks like you have a sharing violation of the QVF file "PROD_DATA_SIZE.QVF" are you sure you only use a single Desktop client to access the qvf ?

Jim Antonakakis is the one that actually built the applications in Qlik Sense desktop but my understanding is that everything was built on the same machine running the same Qlik Sense Desktop client.
