I'm having the same problem as you. Something similar happened with the last Atmosphere and sigpatches update. Many installed games (mostly Nintendo brand) were said to be corrupt. That time, deleting the games and reinstalling solved the issue. Same as for you, this time re-installation fails with both Awoo Installer and Goldleaf.
I'm guessing we need updated patches, but if anyone solves this problem another way, please let us know! Thanks!
UPDATE:
I solved this problem, at least for me. It turns out the problem was the game files, not the sigpatches. It turns out, the games I was having problems with were cartridge dumps converted to NSP files. When I tried with official eShop version NSP files, the games installed properly. Hope this helps and works for everyone else having the same problem!
