Error: Running on Unsupported OS. OS is not Windows 7 or later

​Setup & Installation

1. Installed Wine-2.15 staging via package installer 
2. pass in WINEARCH=win32 and WINEPREFIX=[some perfix] to winecfg. Directory is
not pre-made, so Wine created the directory and did the work. 
3. chose Windows 7 and enabled CSMT, VAAPI, EAX under "Staging" tab in winecfg
3. Used Winetricks to install vcrun 2005 - 2015, vcrun6, vcrun6sp6; msxml4 and
6;msc40 and 42 to run Clip Studio Paint 1.6.2

Installed Clip Studio Paint 1.6.2 and started the software with stylus on
tablet ready for use.

Running the software

I got an error saying "Running on unsupported OS. OS is not Windows 7 or later"
 --- This software runs on Windows 7. I ran this software on a Windows 7 64bit
machine before.

Clicked passed it, and the workspace loads but I couldn't draw on the canvas. I
get no response from either stylus nor mouse.
