You continue to post the same question multiple times in multiple forums. That is, imho, a bit rude and inconsiderate.
Since you asked for help with an IVI driver, I assumed that you might know what you were talking about. I'm not going to get into all of the details (you can look them up) but there is a difference between an IVI driver, which is written in C, and a native LabVIEW driver, which is completely written in LabVIEW. Since 5.0 doesn't support IVI, you would have to use a native LabVIEW driver. Someone has already posted the driver in 5.1 format which means you are most of the way there. Download that driver, and in a new post (in a single forum), attach it and very politely, ask if there is someone who can convert it to 5.0. It will take someone who still has 5.1 installed to do the conversion for you. If no one can do this, then you're left with trying to write some code yourself. Controlling a power supply is usually pretty simple. They don't have a large command set and an experienced programmer could probably write something in a couple of hours. I realize that you are not experienced and it would take you longer. Look at the shipping examples for VISA and GPIB communication and study the instrument programming manual. The basic protocol would be to use a VISA Open. The VISA Open, followed by a VISA Write. For the VISA Write, you send the command that find in the manual. For example, to reset the supply, you send the command *RST. If you send a command that tells the instrument to return a value, you would follow your VISA Write with a VISA Read. For example, you send the command MEAS:VOLT? and then the VISA Read will return tha actual voltage.
