Hello! I’m trying to perform a Market Basket Analysis using transactional data. These are the steps:
- Import data set
- Filter columns I don’t need
- Group Product IDs by Order ID
- Use the node Cell splitter
- Use the node Association Rule Learner (Borgelt)
When I execute the fifth step, this is the error I see:
ERROR Association Rule Learner (Borgelt) 2:5 Execute failed: External program failed. Output: C:\Program Files\KNIME\plugins\org.knime.ext.itemset_4.0.0.v201905311239\resources\executables\win\x86_64\apriori.exe - find frequent item sets with the apriori algorithm

Can anybody explain to me what it is wrong with this? Thank you in advance
