Problem with VISA: error code -1073807202

[misio-pysio]

I have basic problem with VISA, doesnt matter which VISA block I am using, always get an error. Even with the most basic VISA Find Resources, when I try common test for Serial/GPIB/Vixie ports, sending command ?*INSTR, I get error code  -1073807202. I tried tracing the program flow, VISA Find Resources seems to send the query to ports but this is the respond (sometimes even Find Resources blocks the program flow and error code 1 is output, but this is rare and happens only with LabView 4). I am running LabView8 Eval and  WindowsXP Pro. I cannot think about anything I am doing wrong, this is basic test for ports and should just return 0 counted devices when nothing is connected

PLS someone help me:)

The error means 'A code library required by VISA could not be located or loaded.' and you usually get this error when you haven't installed VISA. If all that you did was install the eval version of LabVIEW, this does not install any hardware drivers such as VISA, DAQmx, etc. Get the latest version here.

Yes you are right about the code description, I just didnt have a clue what this actually means. Thx a lot for help, I havent installed VISA on my machine, i just assumed it is an integral part of labview

Many thanks! and hope its gonna work
