Some Vis are not responsing after upgrading to XP

[kdyke]

Hello, My system has just been upgraded from Windows 98 to XP. When the AVG virus checker automatically updates itself, any open vi returns the error message 'Not Responding'. When this vi is reloaded the same message is returned. I have tried using a backup copy of the vi and re-installing Labview but this has not solved the problem. Any ideas?

Hi Kevin,

Which version of labview are you using?

Could you please post the VI's that aren't responding?

I want to try and recreate your problem in order to find you a solution

Thanks

I am using Labview 6.1

The problem is with any vi that uses visa comms. I have tried disabling the virus checker and this makes no difference. I have loaded a vi which doesn't use comms to which I was able to added more components. Swapping between the front panel and the code caused no problems. Then I added a visa resource. When I pressed Window on the menu,  Labview hung and after a short while reported 'Not responding'. I used the task manger to end Labview and the cpu usage was reported as 100%. Cpu usage then dropped to 19%.

The application uses rs232 and GPIB. The GPIB modules are not mis-behaving.

I have XP on a laptop and Labview runs ok.

I do not known which version of visa I am using. I am using the vis in the serial folder in the instrument i/o folder on the function pallette. Placing the vis is not a problem , it is when I place a visa resource on the front panel, or a visa constant on the diagram that crashes Labview.

Hello Kevin,

you can find the used VISA version in the Measurement and Automation Explorer under Software-->NI-VISA. The current version of NI-VISA is 3.4.1. If your version is a much older version download the current version and update NI-VISA. Maybe it helps.

The latest version will not install.

The program setup.exe returns the error message:"The instruction at "0x%08lx" referenced memory at "0x%08lx". The memory could not be "%s."

We have this exact same error after installing CVIRTE 8.0.0.273. Fortunately, one of our engineers found a workaround that works.

We are able to get the other NI installers working again if we delete everything in the following folder:
'\Documents and Settings\xxUSERNAMExx\Local Settings\Temp' except systemfolders like cookies, etc.
