Have gotten it to work with Quest1 + Airlink , but you need to adjust some Windows settings to get it working
Got this article from DLSite where the game is up for sale:
You must be registered to see the links
Open Control Panel -> Clock and Region -> Change date, time... -> Administrative then change system locale to Japanese, don't check the Beta box and restart your computer.
Basically this sets your system to use Japanese if a program isn't using Unicode, which got the game working for me.
Pretty lackluster as a game right now though, just fluid dumping and a bit of sex only in 3 positions as of now. If you don't want to do all of this, don't bother.
