hp816x.llb driver broken after 6.1 upgrade

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).

I have similar problem with upgrading to 6.1. This was how I fixed the problem
-remove all old LV stuff
-re-install old drivers (I used DAQ driver CD in my case)
-install new drivers(or LV 6.1)

hope that works for you

If you have not done so already, you may want to run a mass compile of your VIs since you installed a newer version of LabVIEW.

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.
