TradeStation 10 installation failure: "Unable to register servers" (COM/OLE Registration Error)

[chi-mali]

Hello Bottles Team,

I am attempting to install TradeStation 10 (Trading software) on Fedora 43 using the latest Bottles (Flatpak) and I've hit a wall during the final stages of the installation.

The Problem:

The installer proceeds until it attempts to register the platform components, at which point it fails with the message: "Unable to register servers. Setup will now abort."

Technical Details:

Runner: Soda 9.0.1 (also tested with GE-Proton9-25).

Environment: 64-bit Bottle (Application template).

Dependencies Installed: .NET 4.8 (Verified with NDP48-x86-x64-AllOS-ENU.exe), vcredist2019, vcredist2022.

Issue: It appears to be a 32-bit COM/OLE registration failure. 

What I've tried:

Manually running regsvr32 ORPLAT.dll via the Bottles command line (returns 0x80040154 Class not registered or similar OLE errors).

Disabling mscoree in DLL overrides to force the native .NET installation.

Renaming mscoree.dll in System32 to ensure the Microsoft installer was used.

Since TradeStation 10 relies heavily on WebView2 and 32-bit COM interfaces, is there a specific environment configuration or a hidden dependency I am missing to allow these servers to register correctly in the Wine registry?

Appreciate any insight from anyone who has successfully registered complex 32-bit trading platforms!
