А я вот такую шнягу нашёл:
to the one who wrote that:
please explain how this should work. first of all, the demo doesn't come
with an installer, therfore you can't "install" the demo. if you unpack
the archive you won't find any .dll.
to the ones longing for cinema 4d r9:
if you find a file on your machine called "dsmcr.dll" i suggest you don't
alter any content for it is not part of cinema 4d. i don't know what it is
good for, but it surely won't crack your demo.
i couldn't find the file on my machine anyway.
if i'm wrong please don't hesitate to tell me, 'cause i would love to
play with cinema 4d r9.
original content:
"Follow these instr.:
1) Install the demo
2) Open dscmr.dll and change the value in the line n.23 from 01 to 05
3) save changes
4) start c4d and during the first 5 secs. hit TAB key
That's all! Now you have full install."
