Error Message Launching Signal Express

[JAGLM]

We downloaded Signal Express 2015 for use on an old Windows XP system.

We are able to launch the software but immediately encounter this message: 

Does anyone have any ideas? NI Tech Support hasn't been super helpful so far...

Hello,

Try to uninstall LabVIEW, Signal Express, and install it again. Also, install DAQmx.

I wonder what was the problem with NI support?

I think WindowsXP is not supported anymore, this is why support couldn't do anything so far.
