Well you are not alone, although I can install and run the app....on Windows 10....BUT it refuses to record most things. I DID get a few recordings to complete but up to now it crashes the service app :-O. I also have been working with their 'support' for a LONG time. In fact I first tried this app probably a year ago and ran into similar issues back then (on Windows 7/8/8.1).
The promise of this app is amazing - if only they can finally get it working properly. I signed up for a lifetime membership right from the start, so am fully paid up :-O - but can't use it - VERY frustrating....
Anyone able to install Playon.TV after updating to Win. 10? I've been working with their support since last October (2015) and still can't install it. It says it can't uninstall the old version. I've tired about everything. They've closed my ticket a couple of times and haven't replied to me now in over three weeks. Surely I'm not the only one with this problem!
