NowTVPlayer won't install - RegSetValueEx failed; code5

[Altnacraig]

I've downloaded NOWTVPlayer but when trying to install it on my PC  I get most of the way until this message:

Error writing to registry key

HKEY_CURRENT_USER\Software\Classes\nowyvplayer

RegSetValueEx failed; code5

I've cleared the cache and rebooted the router. NOWTV is fine on my android tablet and is fine on the NOWTV app installed on my Samsung TV - but not on my PC nor my laptop!

Help please - for an amateur!

Thanks very much

@Altnacraig a cursory search on Google may help you. It seems you either don't have administrator privileges or your anti virus is blocking that reg entry.

Instead of clicking on the install.exe (or whatever it is called), try right-clicking on it, and choosing Run As Administrator.
