I am a beginner to AIMMS and was trying to create the Softdrink Planning model by following the procedures in AIMMS_tutorial_professional.pdf. However, I was stunk at specifying the table name attribute step in tutorial page 77/217. Whenever I click the “Table name” wizard, a window will pop up saying “Error opening datasource data\\Softdrink Planning.dsn make sure this is a valid datasource”. Anyone knows how to solve this issue? Your help would be highly appreciated!

I also tried to click the “Table name” wizard in the completed project model but I still have same issue.
