I was able to install and operate ProfitChart One, trading platform on both Ubuntu 18.04 and Linux Mint 20.0 with PlayOnLinux. Only glitch on Linux Mint 20 refers to error msg : Error loading libcef.dll error code:ox0000007E
On POL Debugger report, it shows a problem with Gecko - Could not find Wine Gecko. HTML rendering will be disabled.
Other than that error msg, the aplication is running well. The wine error msg is kind o annoying.
On a Dell Inspiron notebook with Ubuntu 18.04 out of the box installed this very same aplication, exactly the same way as on Linux Mint 19.3 and 20.0 (adding libraries as bellow)
