Hi Christian, 

You may not be aware that some of our controls have been deprecated as of the 2012 Vol. 2 release. 

Jason has a blog that will give you some background on the process of retiring controls which starting with the 2011.2 release.

WPF xamChart and xamTileView specifically were deprecated starting with this release of 2012 Vol. 2. 

If you are using either of these I would recommend that your review the xamDataChart and the xamTileManager which are the current controls. 

Jason provides some links to comparisons of controls and descriptions of the new controls. 

You may also want to review the section in our documentation specifically for the xamTileManager.

 And for the xamDataChart

 Your option now is to manually replace the retired controls with the current controls.  If you attempt to use the Version Utility 2012.2 you should receive a warning message and the log file will show “No matching assembly located in available assemblies InfragisticsWPF4.Tiles.v12.1” 

Please let me know if you have any questions.
