Upgrade or Update Project generates a error for controls

[Sean]

I know that this is not the exact wording of the pop-ups and drop-downs.
I get a drop-down from Telerik in visual studio stating that there is a new update; I select ok.  Even if I go and update the project from the menu bar, I get the error when I run up the page. Sometimes I will see the issue right when looking at the page in design mode.

The way I have been fixing the issue,  delete  the reference and reassociate the Telerik reference.  I believe that then the project is not using he newest Telerik controls.

 I have no custom skins or controls.

Error:

Telerik.Web.UI.RadTabStrip with ID='RadTabStrip1' was unable to find an embedded skin with the name 'Forest'. Please, make sure that the skin name is spelled correctly and that you have added a reference to the Telerik.Web.UI.Skins.dll assembly in your project. If you want to use a custom skin, set EnableEmbeddedSkins=false.

I forgot to mention that deleting the assebles does not work either.

Run to clean with the following Clean.bat

<code>
rd /S /Q "%localappdata%\Microsoft\VisualStudio\9.0\ProjectAssemblies"
md "%localappdata%\Microsoft\VisualStudio\9.0\ProjectAssemblies"

rd /S /Q "%localappdata%\Microsoft\VisualStudio\10.0\ProjectAssemblies"
md "%localappdata%\Microsoft\VisualStudio\10.0\ProjectAssemblies"

 </code>

Supports Answer:

The reason for the experienced problem is the following. Starting from Q3 the skins are placed in a separate assembly. Please, see the following sticky thread on the subject: Separate Skin Assembly in RadControls for ASP.NET AJAX with Q3 2011. You should copy the Telerik.Web.UI.Skins.dll assembly in the bin folder of your project.
