Hello everybody,
I’m using Windows 7 32bit computer. I can’t find any 32bit download options. Can you guys help me please?
Thanks and have a nice day

You can’t use Unity 2017.x on 32 bit computers anymore. Your best bet would be to click this link and use one of the later 5.x releases.

What’s your processor? If you happen to have a processor with 64-bit support you could move to 64-bit Windows.
I imagine that anyone who’s still using Win 7 32bit is using it because they have no other choice.
I’ve had it happen once or twice where an individual was on 64-bit hardware… but more likely than not he’s on a system that just isn’t capable of it.
Since x86_64 has been the standard in CPU’s since 2004, this is most likely the case. If not the 32 bit OS user is in dire need of a hardware upgrade.
Thanks i found 32bit versions of Unity , but whats differences between newest versions?
I have Intel E7400 Core 2 Duo (2.80GHz 2 Cores, 6MB Cache)
The newer versions have more features for sure, and some bugs fixed.
It’s sufficient to develop with, but as others have mentioned, a 32 bit OS is an antique.
Putting the fact aside that Unity stopped building 32bit builds for the editor, the main problem is RAM and “address space”.
Let assume for a moment that Unity would still publish 32bit builds.
32-bit systems can only address up to 2^32 bytes (4GB) of memory even if you have more installed in your computer. The OS just won’t be able to recognize/use it; and due to some other technical details the real usable space is sometimes even less than those 4GB.
When I just have my browser open, multiple visual studio instances, and Unity, I’m already at 10GB…
Sure you could close some things but a development computer generally has to be a lot more powerful than a normal users computer. Overhead from debug-assemblies, the Unity-Editor and its Profiler, extra applications that you’ll need (VisualStudio or at least MonoDevelop, and maybe some image editor) all contribute.
Even if you’re “just” making a small 2D game, the normal development overhead alone will quickly eat up all your RAM.
If you ask me, there’s simply no way to work efficiently with less than 16GB RAM (at the very least), but that’s just my personal opinion and obviously heavily depends on your workflow and tools.
I have 16 but I rarely use more than 4 - I tend to keep only programs I’m directly using open. Old habits die hard. My brother however, keeps 50 billion tabs open and every app known to man.
You can tell he’s probably been using macs.

I agree, < 4 GB of RAM is going to cause problems for the developer. But do you really need 16 GB?? My laptop has 8 GB and I use as my main (mobile) dev station. I purchased it last year in the fall, and came to find out this fall that it was manufactured in 2015. I had to look up the i7-5500U processor that it has to find that out.
Well when I need it, it’s there, and it doesn’t cost anything different to have 8 or 16. 10 bucks? 20 bucks? may as well be 16.
16 is a potential limit because some form factors can’t support more (small motherboards) or the system was bought with old memory they want to get rid of, so they install 2x8gb or 4x4gb or whatever.
In other cases (especially with older or cheaper ram) smaller amounts of ram was faster. These days I’m not sure it’s good to base a decision around.
Generally I tend to buy or build a system and not upgrade the separate parts as generally it’s diminishing returns for me (only as fast as your slowest part).
I’m assuming most of the people in this thread throw out their hardware every time they get something shiny.
I have 64 bit, I still use 32 bit(Not for unity anymore though).
My acceptance of dropping 32 bit Unity comes from having to keep 2 engines constantly, and equally updated.
This may or may not be a real reason it got dropped, but I don’t care.
What I care about is the people that think hardware that cant run the newest CoD with max video profile is worthless.
It’s not worthless, you just need to stop getting distracted by the flashing lights in commercials.
I wouldn’t even need 64 bit if it wasn’t for Unity, and Windows.
Also, I miss Win XP. It came on one cd. ONE CD PEOPLE!!! And it didn’t take 4 gb to run windows services.
I agree @verybinary . I don’t throw out old hardware though. I just it back in the box the new stuff came in and shelve it. Not sure if I’d ever have need for the old hardware but I keep it around.
I’m certain that Unity 5.x probably will publish 32 bit builds too. I suggest that the OP maybe download a Unity 5.x version and try it for him/herself. Don’t listen to our opinions, try it out! =D
Well the only reason you’re still 32 bit is because MS made more money still keeping 32 bit around for businesses that have nothing to do with you. This is why you have 32 bit, and why MS kept making 32 bit operating systems for a decade longer than they needed to. These businesses had 32 bit apps and were not willing to upgrade those apps
Fast forward and modern 64 bit os can handle both 32 and 64 bit just fine, fingers crossed
If buying some new parts saves me a lot of time in the long run i will always do it. As a result for game dev i would recommend 16gb. I can still make do on my macBook that only has 8gb’s of ram but i have to work differently and it does cost me some more time.
While on my main computers, i can run Unity, Rider, Photoshop, Maya and any other supporting apps i need without issue and generally got a good 20 or 30 chrome tabs open. It really helps to have the ram to allow me to do this, it also enables me to use some of the more ram hungry features of said programs as well like solution wide analysis in Rider.
Also i am by no means dumping my computer every year for the latest and greatest, my 2 main desktops are using 3rd and 4 gen i7’s and thus have processors and motherboards that are 5 to 4 years old, and the only upgrades i have made were adding ssd’s and a new gpu.
also @n3pix that processor you have listed does support 64bit so the 64bit Windows 7 would run on it.

Your processor is capable of running Windows 7 64-bit. If you have the necessary discs I recommend backing up your files (because upgrading between 32-bit and 64-bit will wipe your files) and then upgrading to 64-bit.
How many applications do you work in simultaneously? One thing to keep in mind is that a desktop can easily have multiple monitors (laptops are capped at one external unless you have DisplayPort) and that can easily lead you to having Unity, a modelling program (eg Blender), an artwork program (eg PhotoShop), and so on.
Remember you need enough memory to handle these programs and the content you are developing in them.
Since mine are invariably way more powerful than the average rig in my area I often end up giving away my older hardware to either local rummage stores or to friends of mine and my family. At one point I was keeping it around but I eventually realized that I simply never went back to it even when my main rig experienced hardware failure.

Perhaps when you bought it. It’s more like $80-100 for 8GB - $190 for 2x8GB for the most recent systems, $160ish for 1x16GB.
But yeah, max out the memory no matter which system you have. Your OS will use it, and you can keep more related software open at the same time (your 3D modelling, art and game development tools all at once, without swapping out of RAM). What isn’t used for apps becomes disk cache, and with how smart operating systems are now that means a little more performance boost when using the same assets over and over.
A Core 2 Duo system uses DDR2 RAM, though, which is much more expensive when you can even get it. It’s probably best to upgrade to a DDR4 system nowadays. Even a mid-range laptop will be an improvement over many CPUs of that era.
