Change name of library
When trying to change the name of a custom library I have made I get the error "The library is in use outside the project". My questin is, can the name of a library even be changed?
Yes can change it in CBM without any problem it will auto rename for the subbranches which you have in your program,
if you are still facing problem in renaming take a copy of library and save and rename it and can be found out in this location, can insert and used in your logics.

After making these steps need to change the link in the object type structure.
