It's not an issue of Windows 7 because I got Ai CS3, and KPT 1.5 installed and works fine.
Does anyone can help me to resolve this?
Thanks in advance.
Are you sure the KPT 1.5 is compatible/applicable with CS4? If not, there may be an update, if you are lucky.
I tried to find if KPT 1.5 it's compatible with CS4, but I didn't find any info about. It's a shame, because the 3D effect in Ai, isn't so practical as KPT, meanwhile, I'll got to keep Ai CS3 installed...
