Can HRDP Remote be in stalled on a tablet?
No, the application can't be installed on a tablet that's not running Windows operating system (not RT). I've checked Android and iOS store markets, but the application doesn't appear to be available at all.
On the official page, only the Windows version is available for downloading: https://secure.tkfast.com/faqs_view.php?id=152
There is HRDP-Fusion that you can test for tablets (running on Android): http://hrdp-fusion.android.informer.com/
No, I don't think so, it is not suitable for this
