if thats true, then u doesnt download the game with my link right?
cause theres 2 possibility for that error installing dlc
1.the game has many version like US,JP,EU etc. and u must match the game and dlc version, ex: if u have game that are US version and ur dlc are JP version, u cant install the dlc
2.prodkeys not installed/ur using old prodkeys, latest prodkeys version is 18.1.0 prodkeys are very important for switch emulator
