Tom, The NI-VISA library (visa32.dll) will fail to load because a registry key it is trying to open with read/write access privilege does not work for Guest users on Win2000. To solve this problem, do the following steps: Step 1: Log on the computer as the administrator. Step 2: Explicitly grant the guest account write access. To do this, run regedit32.exe, go to HKEY_LOCAL_MACHINE\Software\National Instruments\NI-VISA for Windows 95/NT. Choose the Security>>Permissions menu item. If "Everyone" is present, double-click it and modify the permissions to "Full Control". If not, click "Add", choose "Everyone", and give them "Full Control". If the full control (read/write access) on this key doesn't work, they try again with just read access. The write access is only used for one special feature that we may not support for that type of user. I hope this helps. Have a great day.
Is there any way around this (automated during Visa installation or otherwise)? I have no problem changing the security preferences on my computer, but we're planning to distribute runtime executables with our products and we don't want to inconvenience our customers.
