Hi there,

I'm working in a pretty big IT shop and it appears that 32 Telerik.WinControls where installed with version 2014.2.617.20 by one of the IT staff here.

The downstream issue I'm having is when trying to run the latest Telerik Demos App "Demos - Telerik UI for WPF", I get a DLL mismatch error.

Could not load file or assembly 'Telerik.Windows.Controls, Version=2016.1.112.40, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies, The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040).

I was able to trace back via my log files that this was the file that was used to install these assemblies:  "Telerik_UI_for_WinForms_2014_2_617.msi"

I want to mainly run the demo app to show to influential business partners what Telerik Controls can do, but these current ones installed on my GAC are blocking me from using the WPF Demo App

Would the best course of action be to find this MSI somewhere, and un-install it, or download it from Telerik (if it still exists)?

Or, is the conflict something else?

Much appreciate any feedback someone can provide.

Cheers!

Hi Adam,

The situation you're describing is quite strange -  it seems you have UI for WinForms installed on the computer, but it shouldn't prevent running WPF Demos application.
Still, you could try removing UI for WinForms from GAC as explained in the Add/Remove RadControls to the Global Assembly Cache (GAC) topic.

Additionally, the error could be caused by some files left from a previous installation of the WPF Demos application. I would suggest you to ensure that the old version is completely uninstalled and the cache is clear before installing the new one. By default, the files of the ClickOnce application are stored at <drive>:\Users\<your_user>\AppData\Local\Apps\2.0.

Try it and let us know how it goes.

Hi Yana,

I finally was able to get someone in our IT shop to un-install the Telerik assemblies from the GAC.

The error unfortunately continued after a re-boot.

I can remove the possible left over files from an old version per your second note.

Can I blow away everything under this path?   <drive>:\Users\<your_user>\AppData\Local\Apps\2.0.

Just want to be certain because these files aren't named in a way that makes it obvious what they are :)

Thanks,

Adam

Yana,

 

It turns out that all that was needed was a simple "UnInstall" of the "Demos Telerik UI for WPF" app via Control Panel: Programs and Features.

"Something this complex should always be easy right?  In reality, it's the other way around"

Thanks,

Adam
