I wanted to use After Effects and Premire for more solid video editing, but I have a 32 bit version of Windows 8.1. I found a page about CS5.5 Support for 32 but Windows but I'm not sure how to follow this tutorial before buying the software. I wanted to make sure it works on my 32 bit Windows before I purchase them.
The last 32bit version was CS4. You are looking for something that doesn't exist and well, if you are serious about getting into video editing, going 64bit will be inevitable.
Only thing is that I have too much important files on my PC to make an upgrade to x64 windows. I have a 64 bit CPU but the thing is that I incidentally installed a 32 bit Windows 7 when I replaced my hard drive.
If your files are so important, of course you have them all backed up.
Make an extra backup. Install 64 bit Windows.
