CfgMgr32.dll support

Hello everyone,

we have to port an old windows driver from 32Bit to 64Bit.
This requieres the use of the CfgMgr32.dll.

There once was a delphi-implementation of the CfgMgr32.h, but in the current version RAD 10.3 I can't find it.

So is the CfgMgr32.dll somehow still supported in RAD 10.3 or later?
If so, how can I use it?

Kind regards,

Marcel.
