Have my SW (Delphi 2007 based) xxx times running & tested on various Windows OS 32 /64 bit and Win 10 and Preview.

1. On Chinese Win 7 / 64 bit it works as expected

2. Now on Chinese Win 10 / 64 bit I get on application startup an EReadError in Module rtl100.bpl:
Error reading StatusBar.Panels

a) System Error 1407 using Vista 2.. Win 10 compatibility mode

b) System Error 6 using XP compatibility mode on the main exe

System Error 1407 : Cannot find window class
System Error 6 : The handle is invalid

A simple stripped test program using packages works as expected, this means no error given.

The beef question rises, as it looks as the form resource reader gets lost... what may cause this error:

a) MS error
b) my error
