The reason is not very clear. I suggest entering command-line window first, then run Multiwfn as usual. When Multiwfn crashes, from information printed on screen you may find some useful clues about crashing, you can also upload a corresponding screenshot then I will check.

I was using multiwfn to obtain NCI and AIM analysis of some complexes (using an orca gbw file which was converted to a molden input file).
The calculations themselves run fine (like creating the NCI plot or the laplacian). However, when I want to output the results as cube or png files, the program crashes.....

This never happened before, was there any windows update, that might cause some problems here, or are there other system settings I could play with?

All the best,
