There's a driver we use for tunable lasers and power meters from HP (Agilent
now) that has stopped working since I upgraded to 6.1. I tried going to the
Agilent website and downloading the newest version but it still has the same
errors. I can fix it by copying 3 old dlls (visa32 and 2 others) into the
system32 directory, but then that breaks the serial port functionality. Has
anyone else had this problem and found a fix for it? This is a massively
multifunctional driver library so rewriting it is not an option (better to
just stay with 6.02).
