If you’re a modder, keep regular backups of your projects before testing. If you’re just playing custom levels, consider using the base Hello Neighbor game instead, which rarely has this issue.
Users attempting to install the Mod Kit observe the progress bar reaching precisely 45%. At this point, the download speed typically drops to 0.00 MB/s, or the launcher enters a "Preparing" loop before eventually failing with an error message or remaining stuck indefinitely.
The "Stuck at 45%" error is a known behavior within the Epic Games Launcher environment regarding large Unreal Engine deployments. It is rarely a hardware failure. In 90% of documented cases, resolves the issue, as it forces the launcher to generate a fresh manifest file rather than attempting to repair the corrupted one causing the stall.
