Hello, for this Optimal Risk Portfolio - I need help to complete the following tasks in 3 tasks and sub-tasks. Thank you

Make sure the Excel Solver is installed in your Excel through "File"-"Options"-"Add-ins". Do not use the one from the button "Add-ins" in the "Home" ribbon. 2. solve for the Optimal Risky Portfolia A. Use the Solver to maximize the Sharpe ratio in cell $I$13, by changing the cells $4$13-$D$13. (Note that we insure the complete portfalio has a sum of weights of 1 by using cell $$13.) B. In your Solver, use the Evolutionary Method. C. You will need to put upper and lower bounds to all the cells from $AS13 to SDS13. D. Your bounds should limit the weights to be between -1 and +1 (i.e., between -100% and +100%). Let the weight for portfolio GWD, be whatever it needs to be to make sure the sum of weights = 100% E. Launch the solver to find the weights of the Optimal Risky Portfolio. F.Once the Solver is done, copy the volatility of the portfolio and "PASTE VALUES ONLY" into cell $0$20. It is important to copy it as a value. G. Copy and paste as value the expected return of the portfolio from cell $F$13 to cell $P$20 H. The aptimal portfalio should appear an the graph at the right location 3. Solve for 7 different points to create the Minimum Variance Frontier A. Use the Solver. However, this time, the objective is cell SH513. B. Get the solver ta minimize $H$13. C. Add two constraints for the cell SFS13. First, add $F$13 =0.049 and $F$13
