We have an application developed with VISA/C++, communicating with the instrument (66332A) over serial port.

I found that you have to run Connection Expert after the installation of Agilent IO Libraries Suite to make a successful call to viOpen. What i did is as follows

1. Install Agilent IO Libraries Suite (15.0)
2. Run the app. The app reports error VI_ERROR_RSRC_NFOUND - Insufficient location information or resource not present in the system.
3. Exit the app.
4. Run Connection Expert (I did nothing in Expert)
5. Run the app and it works OK.
6. Unistall the Suite
7. Install the Suite
8. Run the app and the app reports the same error
9. Exit the app
10. Run Connection Expert
11. Run the app and it works OK.

I uninstall and install the Suite several times and verify that to make the app works, you have to run the Connection Expert after the installation of the Libraries Suite.

Is running the connection expert a necessary step? We don't want to force our user to run the Connection Expert to get our app run.
