NextPVR v.5.0.4 install

[mame]

I see that v.5.0.4 is available
going to http://www.nextpvr.com/download.html  and clicking on DOWNLOAD  we are redirected to https://forums.nextpvr.com/showthread.php?tid=59389  (???)
I then downladed instead from https://nextpvr.com/NPVRSetup.exe and ...
executing, I get this msg
     

what about?

I got this as well... I rebooted and tried again and it worked.
Essentially that error popped up before it downloaded the NPVR archive, so am assuming it was an issue about accessing the file to download.
Try again and it will probably work

Ok, true, i retried and did.
Thanks.
