Required help: .Net 1.1 application deployment

I’m working in .Net 1.1 application.

The application’s existing development environment is not stable and having same error in most of the pages in page load itself.

I’m having access to the application’s development server  shared folder only.

In my system the application is working fine. So took new build of the application, removed all the existing files in that shared folder, and copied the published files.

But still I’m getting the same error.

 

Error Message:

Server Error in the Application

Method not found: 'Void System.Web.UI.HtmlControls.HtmlForm.set_Action(System.String)'.

Kindly suggest solution.
