B4J Question Coyping a build from Win10 to Win 7 in Virtual Box ... immediate crash

I' have packaged my application using the built-in packager of B4J.
When copying the entire "build" directory to a folder in a VDI image of Windows 7 (VirtualBox V6.140 on Linux 21), the application crashes immediately:

OpenJDK Platform has stopped working
Problem signature:
Problem Event Name: APPCRASH
Application Name: CdF.exe
Application Version:
Application Timestamp: 5bb8a8b0
Fault Module Name: jimage.dll
Fault Module Version:


Now, the good news that if I compile and build the same application from this Windows 7 environment, the application runs without issue.

So my question is: do I need to compile and build from within the target machine ?

Or is the problem related to VirtualBox ... or anything else ?

A big thank you in advance for your answer.

Thank's a lot for your quick answer Erel, much appreciated.

I'll find a WIn7 machine then.
I'll keep you posted.
In the meantime, I wish you the best for this year.
