Run code when defined save values have loaded

I am wanting to run some code to check if the previsously saved file is a different version. I have a cell that I have allowed to save and restore with the version and on loading ideally would check if this is the same as the application.

I can use the Workbook_Open() sub to run on open but this seems to run before the data is populated in the cell, is there a way to run something after this has happened.

Maybe the XLSPadlock_RestoreCustomValues VBA event?

Sub XLSPadlock_RestoreCustomValues()

 MsgBox ("Restoring values...")

End Sub
