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).
Why is that? I haven't done that because I figured it to be a dangerous operation to change everything all at once. Don't they compile automatically anyway the first time you save them in the new version? Or are you saying that that will overwrite the pertinent dll's?

A mass compile will update all of your VIs into the current version. It could be that there are problems with combining VIs from different versions. This doesn't actually happen when you save them. They can stay in the old version. A mass compile is usually a good idea when you've installed a new version of LabVIEW.
