Application.Run "BERT.Exec" Error

[MN3638]

Hello Thank you for this very nice tool!

I have been using Bert without issue. But from this week I have this VBA run time error when I am trying to call BERT. The syntax is:
Application.Run "BERT.Exec", "install.packages('deSolve')"

Error message: Cannot run the macro BERT.exec. The macro may not be available in this workbook or all macros may be disabled.

Anyone can help with this issue? It will be appreciated!

Thank you
