I receive this error: Exception from IBM ILOG Concert: Problem accessing the Excel file when i try to read data from excel i don't know what is wrong 

if any one have an idea please.

I think you asked the same question on stackoverflow here? Please don't cross-post. And if you feel you have to, please at least cross-reference those posts.

Can you please double check that you have Excel installed and the referenced file exists? Please try again with the absolute path of the file. Can you please also show the offending .dat file?

Have you tried upgrading your CPLEX version? 12.6.1 is a quite old version. It may have problems that are fixed by now.

Hello, did you solve this problem. I receive same error as well. I have used IBM ILOG CPLEX Optimization Studio 22.1.0.00 for a year. But this is the first time such a problem has occurred.
