The problem usually stems from a mismatch between the Base Game and the Update NSP. If you installed the base game from a cartridge dump but are trying to apply an eShop NSP update (or vice versa), the Switch firmware often rejects the signature.
Once the patches are in place, a tool is needed to process the file. The most common tool is Goldleaf or Awoo Installer.
After installation, the Switch sees the game as "updated" to the new version number (e.g., v1.0.2).
If you are attempting to update Nexomon on a modified Switch, the "work" typically follows this workflow:

Sigpatches: If your NSP update fails to install or gives a "data is corrupted" error, your Sigpatches are likely outdated. Update them to match your current firmware.
Maintenance Mode: If the game hangs on the logo after an update, try booting into Maintenance Mode (hold Vol + and Vol - while powering on) and then restarting normally to clear the cache.
Clean Install: Sometimes, deleting the game data (not your save!) and reinstalling the base NSP followed by the latest update NSP solves "Software closed because an error occurred" issues. After installation, the Switch sees the game as
