I am ready to help. The problem to me seems an IDL_PATH issue. Would you please verify the following path in the idl.pref file (in default installation, it locates C:\Program Files\Harris\ENVI54\IDL86\resource\pref folder)?
IDL_PATH: + C:\Programmi\CAT_ENVI;<IDL_DEFAULT>
If there is no such statement in this file, would you please add it? Let's me know if you do see this path.
Thank you for the reply. Yes, I have solved the problem.
Hello, I installed CAT 7.3.1. in ENVI 5.4 as per the instruction. ENVI shows CAT tool neither in menubar nor under Display. An extension toolbox has created named ''cat_menu'' (see attachment). But, this icon doesn't work also! How can I fix this? Thank you,
