Hi, I just bought a new computer. Intel Core 2 Duo E6600 Gigabyte GA-965P-DS3 PNY Quadro FX3500 etc.... My problem is that Solidworks 2003 can not find the parallel dongle... "Can not load DLL: slduiu.dll" - And then shuts down. Im quite sure it is problems with the mainboard (or the chipset intel 965P) as I have spent 4 days, 60 hour on installing all programs again and again on three different computers: I can run it on two other computers with no problem but not the new one. I have also move the hard disk from one of the old working computer to the new one and the dongle has not been found. I have installed all the drivers, but it still not found the dongle. But when I return the hard disk back to the "old" computer WITHOUT re-install anything, it work fine again with the dongle. All has the same bios setting - 378/IRQ7 - ECP+EPP - DMA:3 Anyone else with similar problems??? Anyone else with same cpu and Mainboard.. Anyway im very satisfy with its preformace: The computer runs Solidworks benchmark (SPECviewperf 9.0.3) at Mean: 70,48 at heavy overclocking :-p Peter
