From Thursday, May 23rd (05:00 PM CDT) through Friday, April 24th (1:30 AM CDT), 2024, ni.com will undergo system upgrades that may result in temporary service interruption.
We appreciate your patience as we improve our online experience.
Recently MOST of the .pdf files I have tried to read on the NI website
do not open. The error message is "does not begin with %pdf".
I thought it was my old acrobat 5 but I upgraded to 7 and still the
same thing. PC, Windows XP. Two different computers, same thing. Only
NI, all other .pdfs are OK.
