Someone sent me a custom idcl file. If I place it in the same folder as the preinstalled content center libraries it is detected when I create a new project and I can use it without any difficulty. However, when I try to use a custom library folder it does not seem to be tetected by inventor;

Note that the configure libraries window is still pointed at the default install location, for some reason

Many thanks in advance for any help
