Thank you for your answers.
Well - actually I AM using one of Sedoy's standalone version (thanks a lot anyway) of ISTA D and ISTA P, which has launcher and does not require asking for individual license on PM. I do not remember my version number right now - I guess it must be ancient one. I did some diagnosis, and programming using both ISTA D/P and other tools (winkfp, NCS).
The differences between standalone ISTA and other versions (ISPI, iLean, others if applicable) are still not clear to me - therefore I am asking.
Question is what I will get extra after paying for iLean? Is it for example possible to update iLean ISTA to newer version instead of downloading and installing the whole standalone stuff again and again?
What do I get extra with ISPI compared to standalone / iLean ISTA
Any comments will be appreciated.
