Hi,Environment: Windows Vista UltimeSince 3-4 hours, I try ton compile my webpage with INFRAGISTICS controls on Visual Studio 2008, but a fatal error happens.But, I did a mistake and I know it, I actually install the NetAdvantage for .NET vol.3 CLR 2.0and the NetAdvantage for .NET vol.3 CLR 3.5 on the same PC.The error message was: Error3 The type 'Infragistics.WebUI.UltraWebToolbar.TBSeparator' exists in both 'c:\Windows\assembly\GAC_MSIL\Infragistics2.WebUI.UltraWebToolbar.v8.3\8.3.20083.1009__7dd5c3163f2cd0cb\Infragistics2.WebUI.UltraWebToolbar.v8.3.dll' and 'c:\Windows\assembly\GAC_MSIL\Infragistics35.WebUI.UltraWebToolbar.v8.3\8.3.20083.1009__7dd5c3163f2cd0cb\Infragistics35.WebUI.UltraWebToolbar.v8.3.dll' c:\Users\pc69\AppData\Local\Temp\Temporary ASP.NET Files\test11février\0d548812\64c308ef\App_Web_k-_usjyd.0.cs 300After, I uninstall the NetAdvantage for .NET vol.3 CLR 2.0 with the control panel\programs and features\NetAdvantage for .NET vol.3 CLR 2.0But I always have the same error message. But, now, I know its a DLL error. So I tried to delete/uninstall all the infragistics2 DLL inC:\windows\assembly\... and I received another error message and it goes like this: Assembly 'Infragistics2.WebUI.Shared.v8.3' could not be uninstalled because it is required by other applications.So, thank you for reading and thank you for the future helpHave a nice day-Gilles
HI , I am assuming that you want to remove any reference to 8.3 CLR 2.0.
So go to each aspx page and remove any register tags that point to Infragistics.2.*.*.
Then go into your web.config and look at your add assemblies elements and remove any that point to Infragistics2.*
Go you your Bin directory and remove any infragistics2.*. DLLS
Be sure not to delete any Infragistics35 stuff.
