Why Can't I Access My DAQ Functions From a Windows 2000 User Account?

 

Primary Software: LabVIEW Development Systems>>Full Development System
Primary Software Version: 6.0.2
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem: I have my Windows 2000 system set up with an administrator and a user account. When I log into the administrator account all my VIs for LabVIEW 6 work fine, but when I log in as a user, I get a "Function not found in library" error any time I try to use a DAQ function.

Solution: You need to set the permissions for the National Instruments folder on your user account to "Full-Control". You can do this just for the National Instruments folder if you do not want to add control to the whole user account.

Follow the steps below to accomplish this:

1. Log onto the computer as the administrator and open the registry editor (regedt32.exe) by going to Start->Run-> and typing regedt32.
2. Explicitly grant the guest account full control under HKEY_LOCAL_MACHINE\Software\National Instruments. Choose the Security>>Permissions menu item. If "Everyone" is present, double-click it and modify the permissions to "Full Control". If "Everyone" is not present, click "Add", choose "Everyone", and give them "Full Control".
3. Confirm the fix worked by logging in as a user and running the VI that previously did not work.
