I need to install 32-bit NDIS driver onto 64-bit Windows 7 machine. Does it worth trying? (it seems so: NDIS operates with relatively low memory amounts, and - even - int64's are working on 32-bit too). Or will that Windows7 act cowardly and refuse to load the driver?
The actual problem is that I can't get a correct DDK version to produce working code; (up-to-date DDK refuses to work with NDIS 5.1 deprecated functions, older DDK does not include some header files - for my surprise, MS put the needed stuff into IFS DDK, and IFS DDK environment refuses to build AMD64 binaries). But that's for StackOverflow, going to ask there.
