Yesterday,  my creative cloud would not load.  After 2 hours of technical support from Adobe, creative cloud was fixed.  Unfortunately, the fixed was to uninstall all Adobe products, and then re-installing the products.  So I had to install CP 2017 and CP 9.  Support was not aware that they deleted CP, and I was under the assumption that only the cloud products were erased.  Be careful to verify with support about what software they will be removing when they want to do a complete wipe of your Adobe directory.
