Failed to load extension .

Mon, 26 Jan 2026 18:19:17 GMT

Hi all,

My server Qlik v. 11 SR1 (on windows server 2008) always tells me, in the event log file, this error:

Server Started          Timestamp          SeverityID          EventID          Severity          Message

Even the windows event viewer shows the message:

I do not understand what could be the problem. I've noticed that happens when I browse through the web interface. I tried with many qvw file but the problem will occur.

Can you help me?

Thanks in advance

Your document uses an extension object or a document extension, but the extension is not installed on the server. You have to either remove the extension from the document or install it on the server to get rid of the error.

Hi all,

I'm having same problem on my client site after QVS upgrading to V11 SR1.
Can anyone help to solve it?

Thanks.
Steve Kang.

Hi.

We experience the same issue.

The point is that the logs do not tell a) which document attempts to use an extension object and b) which extension object it is required... is there a way to get these information?

Thank you

Hi all,

I have the same problem after upgrading to QV 11 SR1 and today I logged a support case for this issue. According to QlikView Support this is a known issue which was fixed just recently. The fix will be introduced in the next possible service release, but the release date is currently unknown.

do you try to explicity set local group Qlikview Administrators with full control on security of configuration folder C:\Programdata\qliktech w2k8 or C:\Doqument and setting\all users\application data\Qliktech w2k3 or wherever the folder is locate/redirected

I tried to give Full Control to the Qlikview Administrators, but it did not work. I still get the error message.

Hi Steven,

Was any date given for when this fix would be available - or whether it will be available as a patch or only when SR2 comes out? One of my clients servers has stopped a couple of times since going to SR1 and it would be good to remove this error from the events log to rule it out as being the cause of the stoppage.

Hi Steve,

According to QlikTech support the fix will be introduced in the next possible service release. I didn't receive an update from support about the timeline for QV11 SR2, so I can't tell when SR2 will be available.

Hi everyone,

Yesterday, I applied the customer patch(11291) as a solution of this problem, and the result is satisfied so far.
Contact QlikTech support for the patch.

Hi there - thanks for this - I have also received the patch now. The fix will also be included with QV11 SR2 when this is released.

Steve, i have come across this issue today after installing Server 11 SR1 on a client site. I have requested the patch - did it work satisfactorily for you?

Re: Failed to load extension .

stevedark — Wed, 08 Aug 2012 15:51:51 GMT

Hi Brian,

Yes, no problems installing or since installing. I will email you directly with a link to the install, in case it takes a while to arrive for you.

i just installed this on my server and continue to experience the error. Moreover, I can't see the document extensions working via QVS. Any additional information anyone has to get this working is greatly appreciated. Works fine when looking at webview on my local.

Hi Steve, you can send me the link of this patch via email? I'm having the same problem as yours ...

Re: Failed to load extension .

stevedark — Fri, 10 Aug 2012 19:13:02 GMT

Hi Jeffrey - this sounds like a slightly different issue, as what I was experiencing was occuring even though there were no extensions on the page! It may be worth contacting QlikTech support on this.

Hi Gabriel - I believe the version I have is now out of date as Brian seemed to have a higher build number when he received his from QlikTech. He also said that support turned the patch around quickly for him - so I recommend getting it from source: support@qliktech.com

Hi Dark i am also facing the same issue with qlikivew 11 can you mail me the patch link

Re: Failed to load extension .

stevedark — Mon, 17 Sep 2012 06:10:18 GMT

Hi - the link I have has been superseded. Suggest you mail

support@qlik.com with a link to this thread. Alternatively, SR2 is

imminent so you could wait for that?

We have just upgraded from V9.5 to V11.2 SR1 and encountered the same kind of error messages with one particular document.

The solution was to create a new version of the document from scratch by copying and pasting both the loading script and the objects on each tabsheet. The new document worked fine.
