LabVIEW load error 21

[RLD]

I get a LabVIEW load error 21 when running an exe built with LV6.1 on Win2000

The full message is "A dynamic link library initialization routine failed. An error loading DIO Config.vi". The lvdaq.dll has been installed by the installer in the expected location and the file and subdirectory permissions have been set to "everyone". NIDAQ version is 6.9.3.

This only happens when the user is logged in with "User privileges". Accounts with Power User privileges run the app just fine.

What can I change to allow accounts with normal user privileges to run my LabVIEW exe?

Hi,

DAQ is intended to be run under Administrative priveledges. This is because it is necessary to install and configure device drivers (which is an administrative priveledge). You may be able to get around this issue by giving the National Instruments folder read/write permission to everyone.

This is not a sure solution but it has worked for people in the past.
