Hay, I have found a way to install Pinnicale Studio 9 on a windows 7 computer although it runs slow (and i mean SLOW)
First, insert your studio 9 install disk into your computer's dvd drive (if any Autorun Windows apear just close them )
Now click START and open COMPUTER, you should see your dvd drive with the pinnicale logo (under ''Devices With Removable Storage).
RIGHT click the dvd drive and select OPEN from the drop down menu.
you should be looking at the files that are on the disk, there should be an application for installing the softwre with a name like Autorun or Install, scroll down the page untill you find it. (I think its near the bottom of the list)
RIGHT click the install application when you find it and select Run As Administrator.
After doing this my computer started the installer and installed Pinnicale to my computer, I am running Windows 7 Home Premium 64 Bit on an HP Pavilion dv7 Laptop with an AMD Phenom Triple Core Processor.
Pinnicale launches and runs on my computer however as mentioned previously it runs very slow but it could just be my computer's configuration.
Please leave a comment if this works for anyone else.
