MySolution.Win- Could not load file or assembly ‘DevExpress.XtraTreetList.v9.2

Asked By 0 points N/A Posted on -

Good Day Everyone! I am trying to run XAF Windows application to my computer but failed to do it because of an error.

I don’t know how I can get over to this one.

My operating system is windows XP, do I need to upgrade to a new version of windows for me to run XAF?



The following error occurred:

Could not load file or assembly ‘DevExpress.XtraTreetList.v9.2,

Version=, Culture=neutral, PublicKey Token=b88d1754d700e49a’ or one of its dependencies. The system cannot find the file specified.

The source of that problem could be one of the following:

  • The assembly  name that is being used is different.
  • The assembly version that you are using is different and so forth.

This means that the assembly that has been mentioned in the error message is not available  in the application folder, and therefore the remedy will be to copy it from the Developer's Workstation and paste it in that location for the application to be able to work.

The assembly is usually located in the following directory path, and therefore you will need to paste it there:

C:Program FilesDevExpress 2011.2eXpressApp FrameworkSourcesDevExpress.DLLor C:Program FilesDevExpress 2011.2ComponentsSourcesDevExpress.DLL
