Hi,
When I try to launch OME on our server, I get the error 'Parser error: could not load type 'System.Web.UI.HtmlControls.Htmlframe' from assembly 'System.Web, version=4.0.0.0, culture=neutral...'
Some background - OME was working fine prior to a windows update that upgraded the .NET framework to 4.5.2 (we was previously running version 4). It was not noticed for some time after but we now think this has broken OME.
We have uninstalled .NET framework 4.5.2 and re-installed version 4.0. We have set OME to version 4.0 in the web.config file, and in the application pool (currently set to 'classic' mode, although 'integrated' mode doesn't work either).
We are now getting the error above when trying to launch OME. Can you please advise?
Thanks,
Nick.
