Hi Greg,

When I install the HP 34401 Plug&Play driver from the A.10.00 Plug&Play
Instrument Driver CD,
I get a 36,891 byte HP34401.H file.
I see a similar error message on my VEE 5.01 for Windows on Windows NT.

But when I install the HP 34401 Plug&play driver from the WWW
( ... /34401.exe ),
I get a 36,886 byte HP34401.H file.
I see no error on my VEE 5.01 for Windows on Windows NT.

The 2 archives claim to be the same driver revision.  I am exploring why
they install different HP34401.H files, with different text.

---> In the meantime, I suggest using the proven 34401.exe file on the WWW

Hope this helps!
