why would you want a portable version. bet its not what you need.
I have just installed solidworks sp0 >>2.3GB and still need to install the extras and then upgrade to sp4
because I work on several PCs and portable computers, and I don't want to install it on every one. In addition I travel a lot and I often use the nearest game club to do a bit of my work
.The space is not an issue, I have large usb flash. Nevermind this is a little offtopic.
