I am using Creo Parametric - Release 5.0 (connected) 5.0 188.8.131.52
DLL was unlocked on Creo 5.0.0 does not work on Creo 7.0. Get error message as "Creo tool kit application "" was not unlocked before distribution to your site.". Do we need to unlock the dll for every version separately??
Here are the errors that I faced
Creo tool kit application "" was not unlocked before distribution to your site.
For sure this is true, but has nothing to do with unlock (in my point of view). During compile and link your dll code will contain some PTC bits in a very special order. This is done on each link/compile, the compile and linker will raise errors if some functions are no longer available.
For PTC the unlock is required to write Toolkit Applications at all, and that you have the valid license. Because if the special tag is found you must have a license, and the tag will be there after compile and link.
I never tried to do this unlock on renamed lib files 😀
So unlock is required after you have changed your code, every time 😩
