No worries! We will deal with this together. Here are a bunch of things you could do to ensure that the Tally plugin works perfectly:
Check if you have put the plugin file ‘BankOpenV1.tcp’ in the Tally root folder: This should ideally be somewhere in your C-Drive → Program Files → Tally → Tally ERP 9.
Please don’t change the file name.
In Tally, navigate to Configure --> Product and Features --> Manage Local TDL; here, ensure that 'Load TDL files on startup' is set to 'Yes' and see if you have correctly spelled plugin name, ‘BankOpenV1.tcp’, under 'List of TDL files to preload on startup'.
In Tally navigate to Features --> Add-On Features; here, ensure that you have put ‘Enable Sync’ as ‘Yes’.
