If I have a Creo Parametric perpetual license & I want to add Creo PCX Extension subscription only. Is it works? Please Clarify.
this combination must work. The only difference between perpetual license and subscription license is expiration date. Perpetual license does not have expiration date, subscription license has expiration date.
As Martin mentioned, the combination should work. You need to check the license type i.e locked or floating, if it is floating license manager needs to be configured and for locked you can directly configure that in application.
