Im sorry but nothing you are saying there make any sense to us.
You are obviously using a system developed by a third party in DataEase 7.2 and as DataEase is a development tool we are not familiar with what they have done.
If this is just on one machine and the error message is Could not find DataEase the only solution we can offer is for you to re-install DataEase on this device as there might be some files that has been corrupted or destroyed.
We hope this helps.
