February 1, 20197 yr Hello, I found out how to get the MCP-747 run under a 64 bit sytem with P3D V4. You cannot install the USB driver for the MCP under 64 bit system. If you will install a seriell RS232 card with 9 pin connector and plug in the MCP with a 9 pin cable, then the MCP works very fine.
February 1, 20197 yr When I owned one of these, I posted all the drivers and software for it (inlc 64bit) here http://www.mycockpit.org/forums/downloads.php?do=file&id=482
