Reply To: NI GPIB-USB-HS lockup after first command

I’ve re-confirmed VISA.dw6 is present in “C:\Program Files\HTBasic 2021 Trial” folder, and permissions appear to match the other .DW6 files.
Even tried a few combinations of filename capitalizations.
Is there any config which needs to point to this file ?

The only other issue I can imagine is some security protection software preventing access.
