Hello. I have the same problem. This happens when building x64. When building x86, I get the error: Error LNK1104 cannot open the file "zlibstaticd.lib" I think it is necessary to collect for x86 for greater compatibility? Installed zlib libraries using vcpkg: x64-windows x64-windows-static x86-windows x86-windows-static The file zlibstaticd.lib is not in any directory. vc 2019

[MikhailTsvetkov]

It turned out to be assembled, but it starts every other time. A window creation error appears regularly.

[thalysmarciobn]

same problem here... can't create a window

[DemOnJR]

same problem

[mvccogo]

This specific issue is fixed by initializing the window class with zeroes: WNDCLASSEXW wcex = {0}; However after doing that the window simply won't update (will show a black windows if you try to call it as well)

[DemOnJR]

That not solve the problem.

[mvccogo]

It solved this specific issue for me. Are you still receiving the "Failed to create window"? Anyway, the launcher still wont open due to a read access violation in void Main::paint, more specifically in gCache->g->DrawCachedBitmap(gCache->backgroundCachedBitmap.get(), 0, 0);

[DemOnJR]

I spent all day searching the net for Updater, i think tomorrow I'll start learning c#

You can run on debug mode and see whats happen when the debugger is present? I didn't tested on x64 platform, sorry !

[manoharyes]

Hello,

We are also facing same reported issue.

Trying this with x64. But unable to get this working.

Is there any fix/workaround for this?

[brunobertapeli]

Hey guys I am also in need for that. If someone got a fix and could share..

[LukasCCB]

Hey guys I am also in need for that. If someone got a fix and could share..

I recommend finding another alternative. Use the XSolla launcher or the HeliosLauncher launcher. made in Electron.

Is 2 open-source launchers, which really work and are very complete. literally. Well, this one has a lot of problems and you waste more time fixing it than using it.

Use these two that I mentioned, it will be very easy, you will see.

[brunobertapeli]

Well.. Since i didnt find nothing good. I did my own.
