I have installed Anaplan Excel Add-in 4.2 version. But now I am not able to open files which were prepared on Anaplan Excel Add-in 3.4. IF I open a file it closes down automatically.
What is the workaround for this issue?
I am sorry to hear about this issue. You have to convert the file before being able to use it, watch this short training.
If that doesn't solve your issue, please use the "contact support" button in the "add-in help" section of the ribbon to raise a support ticket.
