I installed InDesign CS3 North Africa, and it works perfectly. I tried to install ID2PDF, but it says "InDesign CS3 or CS4 or CS5 is not available in your system. To install PDF2ID, InDesign CS3 or CS4 or CS5 must be installed. Please make sure to install InDesign CS3 or CS4 or CS5 first then proceed with the installation of PDF2ID". The system I'm working with is Windows 7 64 bits. Please, help me how can I resove the problem. ..
