I have a problem with reading the data from the excel file and getting the error message "Exception from IBM ILOG Concert: Problem accessing the Excel file". I am using the Cplex Version: 12.6.2.0 and my excel version is 2013. I also tried on another computer but still could not fix the problem. Does anyone know what is the reason?

Do you run CPLEX on Windows ? – Alex Fleischer Mar 23 '22 at 20:09

yes, Alex. I could not solve it yet. – sorour Mar 23 '22 at 21:30

Does it due to excel deactivation? Since excel always starts with a prompt that you need activation. – sorour Mar 23 '22 at 22:29

Do you have a Mac or a Windows machine ? – Alex Fleischer Mar 24 '22 at 07:31

Check that you haven't got the file open in Excel at the same time - Excel locks the file while it is open – TimChippingtonDerrick Mar 24 '22 at 20:55

@AlexFleischer I am solving on windows 10. – sorour Mar 24 '22 at 21:56

@TimChippingtonDerrick Yeah I checked that also but I am still getting the error when the excel file is closed. – sorour Mar 24 '22 at 21:59
