GPIB write freezes

I'm trying to connect to a temperature chamber with IEEE interface.  When I use the GPIB example VI ("LabVIEW<->GPIB" when you search for GPIB in the example finder.  All it does is use the GPIB Write to write to the device at the address specified, and then delay for 200 ms, and use the GPIB Read to read from the device if applicable) on my development PC, everything is fine.  But when I deploy it to another PC that only has LabVIEW Runtime 8.0 installed, the program gets stuck on the GPIB write (it actually writes the instruction to the device, but then won't get out from the GPIB write.  I used an instruction to change the setpoint on the chamber, and when I look at the LCD on the chamber, the setpoint was set, but the program gets stuck).  I edited the example a little bit and put in status messages so I know where the program was stuck on.  I installed the deployment on my development PC and the program works fine too.  So I think it's something I setup on the other PC.
 
Both PC are using Windows XP Pro with all the updates; IOTech IEEE Card (PCI488) with the same IEEE driver installed.  Both are Dell's computer, just different models, but I don't think that matters, they're both fairly new models (I think).
 
Please help~~

Hello,

On your deployment PC with only the LabVIEW Runtime engine, do you have NI-488.2 installed?  You will need those drivers in order to use the GPIB functions in LabVIEW.  I opened and ran the program here on my PC and it worked fine with my instrument here.

hmmm... I had it installed at one point, but removed it because I didn't think it was doing anything with it since I wasn't using NI's IEEE card.  I will reinstall it on Monday and see if it works!
 
Thanks!!

See if that gets you going.  Hopefully it will.  if not, what GPIB Card are you using and what version of the GPIB drivers did you install?
