Practice First, Optimizing Scenarios, Decision Trees, Theory Behind, Interface overview

While Running the pre-defined scenarios, you can already face some errors which happens when MiningMath tries to communicate with Excel and fails. The reason why it happens is that there are additional windows (like a login screen, an activation failure, etc.) being opened before the worksheet, which is interfering in MiningMath reports generation.

To find out, close the Excel instances completely and reopen it. If an additional window appears, before the worksheet, try to solve what this message asks so that it would fix this interference.

If you have more than one Excel version in place or it’s impossible to use due to a lack of license, it is recommended to uninstall and use another platform, to open the .csv reports generated and do your own reports.
