Several of my users are randomly getting the following error:



Message: An error occurred while creating the main form



Source: MicroFour StrataFrame UI



Inner Exception: System.Reflection.TargetInvocationException: Exception

has been thrown by the target of an invocation. --->

System.IO.FileLoadException: Could not load file or assembly

'DevExpress.XtraNavBar.v8.2, Version=8.2.4.0, Culture=neutral,

PublicKeyToken=9b171c9fd64da1d1' or one of its dependencies. The process

cannot access the file because it is being used by another process.

(Exception from HRESULT: 0x80070020)



File name: 'DevExpress.XtraNavBar.v8.2, Version=8.2.4.0,

Culture=neutral, PublicKeyToken=9b171c9fd64da1d1'

at Aspire.SF.MainForm.InitializeComponent()

at Aspire.SF.MainForm..ctor()



It does not generate the error if the user tries to start the application again. It typically occurs after the application has updated itself (click once procedures). I realize that the assembly referenced is a DevEx assembly, but I was wondering if there was a way to check for this while starting the app and gracefully closing the app or restarting the app without the user getting the unhandled error message.



Thanks!
