Illustrator 32bit on 64bit

#1

I know this is a Photoshop area, but there is just no area I can ask about Illustrator.

I have read other posts here that say 32bit runs on 64bit, however, I want to know if my current CS3 Illy will run fine, or should I go to CS4 Illy since it has been tested (and I assume supported) on 64bit.

Also, I have been trying to understand one thing. Since Illustrator is still 32bit, If I run it on 64bit with 8gb ram using win 7, will Illustrator have free reign over the 32bit limitation of 4gb?
I am hearing that this isnt the case, but would like to get a bit more info on that.

Thanks in advance.

CS3 works fine on 64-bit Windows Vista and Windows 7 machines.

Being 32-bit, it inherently doesn’t have the ability to access any more than 3GB of RAM.

After Effects is 32-bit too and single-threaded, but it (brutally) works around this by spawning multiple processes and assigning them to individual cores, claiming about 2 GB of RAM per core. Illustrator doesn’t do any of that.

Thanks for that :smiley:

Does anyone know what CS5 will offer? Will 64bit be across the board on that release? Hope so… All I seem to find is that it will be 64bit for Cocoa on Mac?

It’s just photoshop and after effects that will be true 64bit in CS5, from what I’ve heard from Todd Kopriva on mograph.net.

one quick question, so CS3 will only work on Vista and above ?? no XP64 support ??

Thanks.

CS3 works just fine on XP 32/64 bit. But all CS3 apps are 32-bit only, meaning they will not really benefit from the extra memory - though AfterEffects uses some workarounds, as far as I know.

And I have CS4 running stable on a laptop with 4gb and XP32bit. Obviously, Photoshop 64bit is not available after installation on that machine.

I’ll modify hvanderwegen a little - the app itself won’t directly benefit, but it should (in theory; homeboy wishes he had a honkin’ 64bit setup) benefit from running in an environment where the OS and other apps are benefitting from it. Much the same way a single threaded app would benefit from other junk being able to run on the other processor. So, Win7 wants a gig of your ram? OK, let it have that gig over there and CS will use these two over here and somebody else can use the other five!

In theory.
