Hi, I have an old v. of Parallels Workstation 6.0.13976 installed on my Windows 7 64-bit. I run Windows NT 4.00.1381 on my Parallel Workstation. It works great except the hardlock Sentinel, for AutoCAD, connected to the computer via PCI-Parallel. I have installed the driver for the PCI-card on my Windows 7, still the Windows NT cannot find any LPT-port that indicates that the hardlock is on my host computer when im logged on at the virutal machine. My old computer (Windows XP 32bit) works like a charm with this configuration. I tried USB-Parallel-port with no luck aswell. Have I missed something? Is there anything I can do? Thank you //J
