Expected Behavior

Installation finishes successfully.

Current Behavior

An error occurred while installing Windows. Please check the logs in ~/.winboat and verify docker logs WinBoat in your terminal for more information. To reset and try again, follow these instructions.

Possible Solution

Solution 1. Add additional check into "Pre-Requisites" window.
Solution 2. Update documentation to include a check whether port 3389 is already in use by any other software
Solution 3. Allow custom port instead of 3389

I ran into same issue, as soon as I stopped xrdpd the installation started fine.

@Alex-Gunn @Otlichno
I've submitted a pull request (removed) that addresses this issue: https://github.com/TibixDev/winboat/pull/removed
What the fix includes:

Pre-installation port conflict detection - WinBoat now checks if port 3389 is in use before starting the installation
Automatic xrdp detection - Identifies if xrdp is the conflicting service
Resolution options - Provides clear instructions to stop xrdp or disable it during WinBoat installation
Installation tools - Includes helper scripts to resolve the conflict and resume installation

This implements Solution 1 from your suggestions - adding a check into the pre-requisites phase so users are warned before the installation fails.

EDIT:
I apologize for this PR. I introduced scripts to address multiple issues I identified, but I now understand your contribution guidelines specifically prohibit adding scripts to the project.
While I was trying to solve real problems, I should have reviewed your contribution policy before submitting. The approach was wrong for this project's standards.
I've closed the PR and deleted the branch. I won't be introducing scripts in future contributions.
