Execution failed: Error loading type library/DLL

[Andrey Cherepakha]

Hi!

My automation tests made with WebAii work fine on my PC. I am trying to execute them on a different PC and get an error.

ArtOfTest.WebAii.Exceptions.ExecuteCommandException : ExecuteCommand failed!
InError set by the client. Client Error:

I tried to uninstall / install libraries. It does not help.

Configuration of two PC seems to look identical: WinXP SP3, IE 8.0.6001.18702

Here is the GAC info regarding WebAii libraries:

  ArtOfTest.InternetExplorer, Version=2011.2.1413.0, Culture=neutral, PublicKeyToken=5339893a7cefe4d6, processorArchitecture=MSIL
  ArtOfTest.ShDocVw, Version=2011.2.1413.0, Culture=neutral, PublicKeyToken=2c87ddee179cbcea, processorArchitecture=MSIL
  ArtOfTest.WebAii, Version=2011.2.1413.0, Culture=neutral, PublicKeyToken=4fd5f65be123776c, processorArchitecture=MSIL

Any ideas what may cause the error?

I have found a post simple-ie-8-navigateto-fails  with similar error. The solution is clear installation on clear PC. Unfortunately, it will not work in my case.

Every little helps.

Thanks.

Hello Andrey,

I can see that you are using an old release of Telerik Testing Framework ( 2011.2.1413.0).
Could you please try to upgrade the version of the Framework on both of the machines and see if this is going to help. 

Hope to hear from you soon.
