Hi Richard,

I am trying to setup the DNN 7.4 environment and I am following this article "http://www.dnnsoftware.com/wiki/setting-up-your-module-development-environment".

When I was download DNN 7.4 Install Package form Codeplex and followed all the steps it's working fine but when I was replace my actual code it give me this error.Then please help me what would be the issue.

Ankit,

I know this is likely way too late, but for sake of anyone else encountering this problem:

Likely culprit is your '/controls/labelcontrol.ascx' control.

If you first **backup** this folder, then go to the DotNetNuke installation package for the version of DNN you have installed (i.e. 07.04.02) --- take the original copy from there and overwrite the /controls/ folder from the original installation set.

If somehow a control there is from an older installation of DotNetNuke you can see the error you pasted here.
