Hello,

I tried to run your code to get a better understanding of how it works, and it threw the following exception on line 83 of Program.cs when it tried to run the GTK UI:

Managed Debugging Assistant 'PInvokeStackImbalance' : 'A call to PInvoke function 'GLibSharp!GLib.Marshaller+d_g_malloc::Invoke' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.'

I first opened the project in VS 2017, and was prompted to download .NET 4.6.2 by several build errors. Those problems were solved after I downloaded that package, but running the project after I did so is when the exception first started popping up.

I have attached the full output log to this issue. Any advice that you might have for me would be deeply appreciated. :)

i keep getting this error:

this happens upon opening the .sln file in visual studio 2015

Downloading and updating is currently broken due to changes in how the manifest is retrieved and handled.

Files in need of a scrubbing:

• ConfigHandler.cs
• GameHandler.cs
• LauncherHandler.cs

No Install Progress is provided. The progress bar should show the file being downloaded.

Due to deprecated functionality where simple string concatenation was used for create FTP credentials, the launcher will crash if the username contains reserved characters such as the @ symbol.

I am not able to understand how to use it from the source. Also the links are not working.(link from launcher utlis)

Clicking a link in the GTK changelog does not open a new window, but instead navigates to the link inside the launcher. This is undesired behaviour, and the launcher should instead open a new window or tab in the user's default browser.

The link is invalid . Please fix .

Launcher freezes when I am trying to upload banner.png into launcher folder on ftp, seems it cant connect to server.
If I remove banner.png from the ftp folder it starts to work again.
If i change config file to your ftp - it downloads banner and everything looks ok.
Any suggestions?
With much thanks!

Sorry if im bothering you with this.

Move/remove web activity before the UI has loaded.

I don't believe this feature is implemented, but I think there should be a way to delete the game folder of all files not listed in the manifest. Some games generate config files that can generate user errors (if the user does something wrong). And/or maybe files listed in manifest with a null or 00000000000000000000 as their md5 will signal that this file is flagged for deletion.

Windows 8.1 is detected as "Invalid" by the config handler.

Currently, the Windows strings and Unix strings are sourced from two different files. NGetText should be used instead, since it is GNU/GetText and supports both platforms.

In an effort to make the launcher more widely usable, BitTorrent should be implemented as a supported protocol.

I know that you have said that this is under the MIT license with the Gentleman's agreement of not distributing this as a standalone product, but I think you are taking the wrong approach by stating it like that. The MIT license has an expectation with those that know about it as being essentially do what you want to it.

A better approach since you want to modify the license is to use one that allows that sort of thing by design.

Here is a site that gives and easy to use breakdown of different open source licenses.
http://choosealicense.com/licenses/

I would recommend using a license like the No License, which restricts most things, but allows you to specifically unrestrict them at your digression. It is essentially a "Build your own" license.

The No license looks like this by default.

Copyright [year] [fullname]

And you just add the specific things you unrestrict after it.

These are the default rules to No License.

How to apply this license

Simply do nothing, though including a copyright notice is recommended.

Huge amounts of code is duplicated between Windows and Unix UI. These should be abstracted out to use a common code base.
Is the best method for cross platform to use two unique UI toolkits? Seems repetitive and counter-intuitive

when I connect to it using the private IP (192.blah), it works perfectly, everything transfers super fast, BUT when I connect to it using the public IP port forwarded on my router, it connects and can transfer small files but completely fails with anything over 4000Kb

The downloading of files from FTP should be away from the UI thread this would allow for simulations downloads instead of 1 file at a time.

Move manifest downloading to Game install/repair/update methods.

The launcher's UI should be updated to GTK3, and as part of this it should replace the outdated WinForms UI.

When installing a game on Linux, the launcher does not switch to Launch mode after the game finishes downloading, nor does the progress bar clear out.

What do you mean by 'root of the launchpad installation' in the in-depth wiki page for the config

All of the launcher's output to stdout and stderr should be redirected to a proper log file and not just discarded.

Implement events for game quit, game crash and game launch.

Due to the location the GUID is stored in (the settings file), the GUID is typically only generated once when the launcher is packaged. The GUID should be stored separately from the configuration file, and should not be packaged along with the release binaries.

Just updating the launcher binary will not work in the future. An installation package approach is more advisable.

Possible solutions:

• Inno Setup on Windows
• .deb package on Linux
• .app package on Mac
• Custom solution using the same Manifest-Server model as the game installation

Upon attempting to run the pre-compiled Launchpad binaries (and the utilities app) under Windows 10 1809, the app immediately closes silently. There's no output to either the command line or the log.

I suspected that it might be due to missing .net libraries, but when I attempt to install it, I get .NET Framework 4.6.2 or a later update is already installed on this computer., with no way to force an install.

So, switching to trying to compile my own version in Visual Studio 2017, I am presented with these errors:

Again, I can't install these libraries for the reason stated above.

I tried installing Mono, as somebody suggested in another thread, but even installing both x64 and x86 libraries made no difference.
