Occasionaly when working in my rainbow installation, I get the Internet Explorer error:

unable to find script library '/aspnet_client/system_web/1_1_4322/WebUIValidation.js. Try placing this file manually, or reinstall by running 'aspnet_regiis -c'.

This file exists in my installation so I don't know why it can't be found. When I tried running aspnet_regiis -c it couldn't be found.

I get this error, for example, when I'm trying to edit collection properties of the language module.

I'm running a brand new installation. (Rainbow 2006) W2K Pro, Sql Server 2000 Eval.

Thanks in advance,

Ed

If you are using .net 2.0 , you will not find WebUIValidation.js as it is embeded in .net framework .
