Hi, We have installed the QlikView Web Parts on MOSS 2007 and QlikView server 8.5 on a seperate server. After installation, we have tested the data pump and recieved the following message. (I notice both do not generate the same output as described in the web site.) Is there a problem on web parts installation? Thanks very much for your time and kind help. Best regards, Margaret. http://localhost/QvsViewClientEx.ashx?test=true (test=true) System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.EnvironmentPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) at System.Security.CodeAccessPermission.Demand() at System.Environment.get_UserName() at QT.QWW.Framework.QvsViewClientEx.ProcessRequest(HttpContext context) The action that failed was: Demand The type of the first permission that failed was: System.Security.Permissions.EnvironmentPermission The first permission that failed was: The demand was for: The granted set of the failing assembly was: The assembly or AppDomain that failed was: QlikWebWorkBench, Version=1.0.0.0, Culture=neutral, PublicKeyToken=89efab03fcdd5bbd The method that caused the failure was: Void ProcessRequest(System.Web.HttpContext) The Zone of the assembly that failed was: MyComputer The Url of the assembly that failed was: file:///C:/Inetpub/wwwroot/wss/VirtualDirectories/80/bin/QlikWebWorkBench.DLL http://localhost/QvsViewClientEx.ashx - No Document

Hi Margaret,

I think this is happening because when the datapump is in this 'test mode', it tries to query for the current UserName but the documentation (incorrectly) does not include the EnvironmentPermission class. So, you could try adding the EnvironmentPermission into your web.config:

<IPermission class="EnvironmentPermission" version="1" Read="USERNAME" />

Alternatively, can you tell me what happens when you actually try to  run the web parts normally?

Hi Chris, Thanks for your kind support. If we leave trust level to "Full", the result comes up exactly presented on the web site. Now I have occured new problem at the QV Chart web parts. It does not allow to modify or add a new chart. It comes up with "403 FORBIDDEN" error message. And aslo the web page is really slow and keep showing "2 remaining items to download". Please can you advise what is causing the problem. Thanks very much for your time and kind help. Best regards, Margaret.
