validator unable to find script...error

Don't know why get this error when I use any validator web control:

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

please help....

Thanks,

Jewel

Look in C:/inetpub/wwwroot/aspnet_client/blah blah blah for that JS file.

the file is there...what do I next?

Thanks

Go to the visual studio command prompt and run

aspnet_regiis -c

Thanks, but now it doesn't show the error message, it just doesn't appear on the web form when I run it.
