Windows 7: Vista Twinhan drivers don't work with 4GB RAM in Win7

Vista Twinhan drivers don't work with 4GB RAM in Win7

A Twinhan 1020a PCI Satellite Card works perfect with x64 BDA drivers in 64-bit Vista on a PC with 4 Gb RAM installed. But after installing 64-bit Win 7 the same card with the same drivers can only work normally when setting less than 4Gb RAM to use at startup in msconfig. Why is that, and how to fix?

What driver are you using in win 7. You can use the vista driver if you install it in compatibility mode.

to do that simply right click the installer>properties>compatibility>vista

The drivers were installed from Device Manager using driver .inf file (see attached). No way to select any compatibility mode in the driver .sys or .inf file. The installer is available, which also installs the same drivers. The tuner doesn't send MPEG stream to any viewer, unless less than 4 Gb is selected in msconfig. And it works correctly in Vista x64. Did you mean that selecting compatibility mode for that installer would do the trick? Could you explain why, if it doesn't fail to install them in Win7? The drivers are supposingly installed the same way by either installer or from .inf file - or they don't? I guess, these are XP 64-bit drivers, but they work OK in Vista with 4+Gb RAM.

With Twinhan company long gone, may be someone can make these drivers work properly in Win 7 x64 with 4+ Gb RAM? It may be just a minor correction, since they work OK in Vista.
