VISA Directories

This topic provides information about the location of VISA software files.

Note: Always use “Add/Remove Programs” from the Windows Control Panel to remove the Agilent IO Libraries Suite; never delete installed files manually.

Windows Directory Structure

Agilent IO Libraries Suite 16 uses the new IVI VISA COM Standard Components. They install both the IVI VISA COM files, and create the VXIplug&play directory structure if it doesn't already exist. The default base directory for the VXIplug&play components in this installer is:

      C:\Program Files\IVI Foundation\VISA

Note that if you already have a set of VXIpnp directories on your PC, the new installer will continue to use your current set of directories -- probably either

  C:\Program Files\VISA      

or

     C:\VXIPNP

and not create a new set in

      C:\Program Files\IVI Foundation\VISA.

The visa32.dllfile (for 32- and 64-bit operating systems) and visa64.dll file (for 64-bit operating systems), are stored in the C:\Windows\System32 folder. The VISA path can be displayed by clicking the IO icon in the Windows notification area. Then click Installation Information to view a dialog box that contains the VISA path information. A typical display follows.

 

Note: Your Agilent IO Libraries Suite Version number may be different and your paths may be different if you did a custom installation.
