I've seen a couple of reports of Solitar being unable to launch on Windows. After investigating, it appears that Windows is blocking certain required DLLs from being loaded.
I haven't been able to reproduce the issue myself, but with this update I've streamlined how Solitar is packaged. Most of the game's dependencies that were previously deployed as individual DLL files are now consolidated as a single executable bundle, which will hopefully reduce the possibility of Windows blocking any of these individual DLLs from loading.
If you're still having trouble launching the game, or if this update causes any new issues, please reach out on the Solitar Discord so I can work with you to investigate.
