Once your environment is activated you could try to do "conda list" and check is cpacscreator is in the list, if not, you can do:
conda install -c dlr-sc cpacscreator

i solved the above issue. now when i run cpacscreator i get the following:

cpacscreator: error while loading shared libraries: libtixi3.so.0: cannot open shared object file: No such file or directory

any help?

I think it is a compatibility issue between the tixi version and the cpacscreator version, you should maybe check this issue DLR-SC/tigl#713
I know that people responsible for cpacscreator/tigl are working on it so it should improve in the future.

Thnx alot. It was solved using the following:
conda install tixi3=3.0.3 -c dlr-sc

I'm experiencing the same problem. When I tried to solve it using your method " conda install tixi3=3.0.3 -c dlr-sc". I'm getting errors like "solving environment:failed with initial frozen solve" . Would appreciate your assistance

u need to update the environments and also conda if needed:
conda update --all
