You can try to install it without help of PlayOnLinux to do so:
1) remove your "~./wine" directory and run winecfg then close it
2) paste "wget http://kegel.com/wine/winetricks && sh winetricks wsh56 msxml3 ie6" in terminal
You can try to install it also with help of PlayOnLinux to do so:
1) download unofficial POL Helper plugin which is at the end of
this forum site
2) install it to your "~/.PlayOnLinux/plugins/" directory
3) Run it out of PlayOnLinux
4) press "Create POL Prefix" and type e.g. "RealArcade" in New POL prefix name
5) press "Create POL Prefix" and close this window
6) press "winetricks" then "To WINEPREFIX"
7) select "RealArcade" as "Chosen WINEPREFIX" and press "run winetricks"
8) then select msxml3, ie6, wsh56 and press OK
9) you can close POL Helper as it will not be needed now
10) press install
11) on the bottom press "Install a .pol package or an unsupported application"
12) choose "Manual installation" and press forward
13) choose "Edit an application already installed" and press forward

You may need to repeat points from 10) if it fails. For me it worked at 3rd time.
It does work with Robinson Crusoe. If it will work for you too then please post test result
