I am getting this message when I run on of the prepackaged sample projects (Oil blending problem) with the spreadsheet configuration. I also tried my own project which reads from spreadsheet with the same result.
I am new to OPL dev studio and hope there is an easy fix for this.
Thank you for any input for this problem.

There might be an instance of Excel locking your .xls file.
Sometimes you have zombie Excel processes, those need to be killed manually.

Hi,

I have exactly the same problem; my model used to work, now I can not load data from Excel any more. There are no Zombies in my process list, and the Oil example is not running any more as well.

Help!

Hi,

I found the problem's solution: repairing the Excel installation instantly brought back the access to Excel in OPL.

All the best,
