How to install Replikanto manually when NinjaScript import fails?

When NinjaTrader shows the error "You have custom NinjaScript files on your PC that have programming errors. These errors must be resolved before you can import a NinjaScript Archive File.", it blocks the standard NinjaScript Add-On import. This error occurs when other NinjaScript files (indicators or strategies) on the PC have compilation errors.

The workaround is to install Replikanto manually by copying its files directly to the NinjaTrader custom folder, bypassing the import wizard entirely. Starting with Replikanto 1.7.0.0, the same Replikanto .zip works on every NinjaTrader 8 version, so use the latest .zip from your downloads page.

Manual Installation Steps

1. Close NinjaTrader completely.
2. Extract the Replikanto .zip file you downloaded. Right-click it and choose "Extract All". In Replikanto 1.7.0.0 and later, the extracted folder contains Replikanto.dll, a pt-PT folder (the Portuguese interface files), ReplikantoCrossOrderRelationship.json and Info.xml. There is no separate FlowBotsLibrary.dll any more.
3. Open Windows Explorer and navigate to: Documents\NinjaTrader 8\bin\Custom\
4. Copy the Replikanto.dll file and the whole pt-PT folder from the extracted folder into the bin\Custom\ folder. Overwrite if prompted. If you skip the pt-PT folder, Replikanto still runs, but the Portuguese interface is not available.
5. Copy ReplikantoCrossOrderRelationship.json only if bin\Custom\ does not already have one. It is optional, and an existing file may hold your own Cross Order relationships, so do not overwrite it. You do not need to copy Info.xml; it is only used by the NinjaTrader import.
6. Restart NinjaTrader. Replikanto should now load normally.
