CC2 transition moment problem

[葉哲和]

Dear Molpro developers,

I wanted to calculate CC2 excitation energies and transition moments. I tried both 2025.3 and 2025.4 but they always gave me an error message saying:

 ? Error

 ? imode_df needs to be set to 1

 ? The problem occurs in cc2_exc_init

I believe this is due to some variable value misplacement in the source code. However, I am using Molpro from a prebuild binary. So no hope for me as so far.

Anyone having clue?

Best regards,
