Good afternoon: Thank you by accept me in this list...I'm new in this list but I have a problem that I hope You can help me: I almost always use GNU/Linux (Ubuntu usually), but I need to run a spreadsheet with macros (.xa) that content the SimulAr program for simulate Monte Carlo methods. When I run the program, I got this message: "Has occurred the error '-2147417848 (80010108)' In time of execution. Error in the RegWrite object method 'IWsh Shell3' " Then I can't start to run the program. I'm running Wine 2.4 dev on GNU / Linux Ubuntu 16.04 with Excel 2003. Do you know how to solve this problem ?. Would you please help me ? Regards, -- Atentamente, Jorge Rodríguez
