Hello LabView Discussion forum. I am currently using LabView 2009. My research supervisor has been attempting to open Legacy files from Labview 7.1 on the more modern version, with no success. After doing a little research, I found that I needed to download Traditional DAQ in order to get the newer version of LabView to open the older file. I first downloaded the DAQ for 7.4.1 and installed it with setup.exe, after which I attempted to open the program. I got the "Error loading lvdaq.dll... Initialization failed" error. I then downloaded 7.4.4, thinking perhaps it would be a better version. Same error. I am now downloading version 7.1 (an earlier legacy DAQ), thinking that perhaps the version numbers ought to match up from the origin of the older file to the legacy DAQ I have to run it. Hopefully this will work (and if it does I will simply delete my post), however if it doesn't, I shall update my post, and hopefully get some help figuring out what needs to be done. I thank you in advance for any assistance rendered.

Well, we tried uninstalling and reinstalling, and it didn't help. Same error. Not really sure where to go from here. We might have to drop back to version 8, or we might give a call in to Tech support.

Stepping up from 7.1 to 8.0 to 9.0 worked like a charm.

The VI loads as expected now. Problem Solved.
