Thought about it, it works for the app just as well. I choose this solution because: 1)I don't know what installed means. Means a 8087 is installed or that an emulator is installed. 2)at least in case 11: the documentation is clear what should be returned. 3)setting installed to 1 enables some assembly code, that could well be the reason that it is now set to zero. This was the original Changelog entry that introduced "installed" : | * dlls/win87em/emulate.c: | Andreas Mohr <[email protected]> | Several improvements. | (25 Nov 1999) Shall I make another patch?
