AddIn

Recently i created an addin for outlook 2013 and a wix installer to perform the installation of the addin. The installation and addin work without any problems in my dev environment but when i install it on another machine and launch outlook the addin is disabled, when i enable it outlook crashes. The only trace i can find of what happened is in the event viewer which reports 2 errors, an application error:

- System 

  - Provider

   Application: OUTLOOK.EXE Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception. Exception Info: System.NullReferenceException Stack: at Microsoft.Office.Tools.Ribbon.RibbonBase.Dispose(Boolean) at TaskMonsterOutlookAddin.OutlookRibbon.Dispose(Boolean) at System.ComponentModel.Component.Finalize()  

I see that there is a null reference exception in the .net error but the exception info is showing the outlook ribbons Dispose method which is auto generated, i realize something is going wrong when then dispose method is being called but im not sure what to look for, does anyone have any ideas on how this can be fixed?. i surrounded the code in the dispose method with a try catch but i didn't gather anything new from the returned exceptions.
