Hello, in the past I have used the trial version of Illustrator and Photoshop versions 5 and 5.5. After each trial period, I tried to remove all the installed files. However, there are some leftover. I have just ordered the Master Collections CS6. While waiting, does it make any difference if I download the trial version and use it now? Is there any way to completely remove all the associated files installed in previous versions? Thank you.
