Please show complete source code of your strategy.

Is this a "good" installation of WL?
Did you try to reinstall in an empty folder?

Coud you tekk me what does it mean? — Is this a "good" installation of WL?

CODE:

using WealthLab.Backtest;
using System;
using WealthLab.Core;
using WealthLab.Data;
using WealthLab.Indicators;
using System.Collections.Generic;

namespace WealthScript1 
{
  
    public class MaxMinStop : WealthScript
    {
      private StrategyParameter period;

      public MaxMinStop()
      {
        period = CreateParameter("Period", 3, 1, 10, 1);
      }

      protected override void Execute()
      {
        int bars = Bars.Count;
        int sessionBars = bars / (int)period.Value;
        var highest = Highest.Series(High, sessionBars);
        var lowest = Lowest.Series(Low, sessionBars);
        var position = MarketPosition.None;
        var tickSize = Bars.Info.TickSize;
        var portfolio = Portfolio;

        for (int bar = sessionBars; bar < bars; bar++)
        {
          if (position == MarketPosition.None)
          {
            if (Bars.Close[bar] >= highest[bar - sessionBars])
            {
              var stopPrice = Math.Round(highest[bar - sessionBars] + 1 * tickSize, MidpointRounding.AwayFromZero);
              var ticket = BuyAtStop(bar + 1, stopPrice, "Buy at Stop");
              Print("BUY at " + stopPrice.ToString() + " Stop");
              position = MarketPosition.Long;
            }
          }
          else
          {
            if (Bars.Close[bar] <= lowest[bar - sessionBars])
            {
              var stopPrice = Math.Round(lowest[bar - sessionBars] - 1 * tickSize, MidpointRounding.AwayFromZero);
              ExitAtStop(MarketPosition.Long, bar + 1, stopPrice, "Exit at Stop");
              Print("SELL at " + stopPrice.ToString() + " Stop");
              position = MarketPosition.None;
            }
          }
        }

        if (position == MarketPosition.Long)
        {
          ExitAtMarket(bar + 1, "Exit at Close");
          Print("SELL at Close");
        }
      }
    }
  }

This looks like a WL6 strategy? They’re not compatible with WL7/8.

Here is a conversion for you:

CODE:

using WealthLab.Backtest;
using System;
using WealthLab.Core;
using WealthLab.Data;
using WealthLab.Indicators;
using System.Collections.Generic;

namespace WealthScript1 
{
    public class MyStrategy : UserStrategyBase
    {
      //constructor
      public MyStrategy() : base()
      {
         AddParameter("Session Bars", ParameterType.Int32, 3, 1, 10, 1);
      }
      
        //create indicators and other objects here, this is executed prior to the main trading loop
        public override void Initialize(BarHistory bars)
        {
         sessionBars = Parameters[0].AsInt;
         tickSize = bars.SymbolInfo == null ? 0.01 : bars.SymbolInfo.TickSize;
         hh = Highest.Series(bars.High, sessionBars);
         ll = Lowest.Series(bars.Low, sessionBars);
         PlotIndicator(hh);
         PlotIndicator(ll);
         PlotStopsAndLimits();
         StartIndex = sessionBars;
        }

        //execute the strategy rules here, this is executed once for each bar in the backtest history
        public override void Execute(BarHistory bars, int idx)
        {
         if (LastOpenPosition == null)
         {
            if (bars.Close[idx] >= hh[idx - sessionBars])
            {
               double stopPrice = Math.Round(hh[idx - sessionBars] + 1 * tickSize, MidpointRounding.AwayFromZero);
               PlaceTrade(bars, TransactionType.Buy, OrderType.Stop, stopPrice, "Buy at Stop");
               WriteToDebugLog("Buy at Stop: " + stopPrice);
            }
         }
         else
         {
            if (bars.Close[idx] <= ll[idx - sessionBars])
            {
               double stopPrice = Math.Round(ll[idx - sessionBars] - 1 * tickSize, MidpointRounding.AwayFromZero);
               PlaceTrade(bars, TransactionType.Sell, OrderType.Stop, stopPrice, "Sell at Stop");
               WriteToDebugLog("Sell at Stop: " + stopPrice);
            }
         }
        }

      //declare private variables below
      private int sessionBars;
      private Highest hh;
      private Lowest ll;
      private double tickSize;
    }
}
