546	Error v. 5.2 on Windows Server 2016	Alberto Bianchi	Jeff McKenna	"Environment:
- ms4w version: 5.2
- OS affected: Windows Server 2016
- OS working: Windows 10, Windows 11, Windows Server 2019

Problem:
Running mapserv.exe from the cgi-bin folder produces:
""The application was unable to start correctly (0xc000a200)""

Investigation performed:
- All required DLLs are found successfully (verified with Process Monitor)
- Executable is not blocked by Mark of the Web (no Zone.Identifier stream)
- MD5 hash of mapserv.exe is identical between working and non-working systems
- Apache starts correctly; only mapserv.exe fails
- ms4w 5.0 mapserv.exe works correctly on the same Windows Server 2016 machine
- Issue is reproducible on multiple different machines running Windows Server 2016

The error code 0xc000a200 (STATUS_INVALID_IMAGE_HASH) suggests that 
ms4w 5.2 may depend on a system API or runtime not available on Windows Server 2016."	defect	closed	major	5.2.1 release	MS4W - Base	5.2.0	duplicate		TC Haddad
