bslegacyutil's Issues

Says newer version is available and crashes

When launching the program it states a newer version is available before throwing an error and crashing.
(the error:
Unhandled exception. System. Net. Http.HttpRequestException: Response status code does not indicate success: 404 (Not Found).
at System. Net . Http . HttpResponseMessage . EnsureSuccessStatusCode()
at System. Net. Http.HttpCIient.GetStringAsyncCore(HttpRequestMessage request, CancellationToken canceltationToken)
at BSLegacyUtiI. Program. args
)
It also opens the releases page of the defunct Github page of the project (https://github.com/BeatSaberLegacyGroup/BSLegacyUtil/releases)

To Reproduce
Steps to reproduce the behavior:
Launch the program

Screenshots

Desktop:

• OS: [Windows 11]

Login running for ever

Describe the bug
For some reason, When I try to login after selecting version, it asks for 2FA - So I enter my code and click enter - after that I get a screen "Sign In" and showing loading icon... this screen runs now forever.... (click on back doesn't work and the X crashes the app)

To Reproduce
Steps to reproduce the behavior:

1. Select Version (1.18.3 in my case)
2. Enter Username and Password
3. Enter 2FA
4. Get endless loading screen

Expected behavior
Download starts

BSLegacyUtil cannot find directory path when installing legacy version

I previously used your utility to successfully install a legacy version instead (I think 1.16.4 instead of 1.17). When Beatsaber auto-updated to 1.18, my install would no longer launch saying some files were mismatched. I verified the files, which led to 75 files being replaced and 1.18 launching properly again. I tried to revert bacj to 1.17 or 1.16 (using BSLegacyUtil on the command line) but cannot. I am able to download previous versions, but the utility crashes when I try to install them. I get the following error:

[BSLegacyUtil] [Error] ====== STACK =====

Any idea what could be going wrong?

DepotDownloader fails to start

Describe the bug
There seems to be a typo in executing DepotDownloader or something similar, preventing it from being executed.

To Reproduce

1. Pick the first option to download a verison.
2. Enter username and password (does not have to be correct)
3. When attempting to execute DepotDownloader, it fails.

[Feature Request] Automated Symlink of the custom songs folder.

If at all possible, could automated symbolic links be created for the custom songs folder and the custom WIP folder?

It could utilize user input of beat saber's install location. but also be completely optional. and allow users to keep song libraries from both versions completely in sync.

The program exits when logging into steam without the .net packages installed

I was walking a friend through backdating and he was having a lot of trouble with logging in, so I'm reporting on his behalf.

Every time after my friend inputted his password, the window would promptly close.
He is on Windows 10.

Installing the .net packages fixed the issue.

Error while moving files.

I am getting this error. Please help.

[Bug] 2FA breaks input

When steam info is entered, it sends a 2FA response if you have steam guard. However, it sends in the input field, so it's still expecting a version number. So if you were to try to enter it, it would just tell you "invalid input"

BSLegacyUtil won't run on Ubuntu

Describe the bug
Trying to run BSLegacyUtil with .NET or Mono will not work on Ubuntu.

To Reproduce
Steps to reproduce the behavior:

1. Download Linux build
2. Extract files
3. Install .NET according to manual
4. Try to run application

Desktop (please complete the following information):

• OS: Ubuntu 21.10
• Version: 4.8.0

Additional context

Depotdownloader directly works fine so I'm going to use that but I thought it was worth reporting since there's a Linux build on the homepage and it seems like it should work.

I'm not sure how it can work since it uses Forms and references Microsoft.WindowsDesktop.App but maybe I'm overlooking something? Changing the framework manually to Microsoft.NETCore.App allows it to launch but of course fails with Could not load file or assembly 'System.Windows.Forms.

Trying to run with .NET:

It was not possible to find any compatible framework version
The framework 'Microsoft.WindowsDesktop.App', version '3.1.0' (x64) was not found.
  - No frameworks were found.

You can resolve the problem by installing the specified framework and/or SDK.

The specified framework can be found at:
  - https://aka.ms/dotnet-core-applaunch?framework=Microsoft.WindowsDesktop.App&framework_version=3.1.0&arch=x64&rid=ubuntu.21.10-x64
