If on windows, which I presume you are, then Install / upgrade it to a 64 bit version of the same OS using the same key.

Unless you are on a BBC Micro or some other dinosaur of a computer, then your system is surely 64 bit.

Edit -

Obviously I don't know the OS you're using, but if its Windows 7 and don't have original media, then you may be able to download an ISO from here (I haven't tried it since I have all my original CD's / DVD's etc)

If you're on XP / Vista, well hmmmm...Not sure...

Simple fact is 32bit can only support a max of 4gb of RAM and that includes running Windows as well. Games like this require ALOT of RAM so making a 32bit version wasn't an option. The advice above is valid, you should be able to upgrade to 64bit for no charge, you will have to backup all your files though. For gaming in 2015 and beyond, 32bit is becoming obsolete.

Hello, following windows version CD-keys allow you to install 32bit or 64bit version with same key:

Windows Vista Home/Pro/Ultimate
Windows 7 Home/Pro/Ultimate
Windows 8 Home/Pro
Windows 8.1 Home/Pro

Also if you have Windows Home version but your friend only has Pro install media, no worries. You can install both versions from Pro, and with Ultimate you can install all versions (Starter doesn't exist in 64bit)

64bit has only benefits
- Better security
- More memory for programs (if you have RAM)
- Supports all 32bit programs
- Supports all 64bit programs

Cons
- 0-1% performance loss on 32bit only programs (you won't notice unless your game runs over 1000 fps :D)

Ok seems like I have no other choice :D
but thanks

I am pretty curious, what is your OS/computer specs and when was the system originally built/purchased?

I am attempting not to troll here, but 64-bit computing is nothing "new". XP x64 was released 10 years ago this month (granted it was OEM only). Vista 64-bit was released in 2006 and I find it real hard to believe that you would have a system that is not 64-bit capable (as in, not have a CPU capable of processing it, since AMD and Intel instruction sets have been around since 2004ish as I recall), yet still be able to play the game at all (old GFX, not enough memory, 32-bit CPU).

I am not saying everyone should upgrade their computer every 4 months, but even 5 years in gaming computer time (without bumping GFX card, more memory, faster HDD, better power supply, etc) is a very, very long time and I appreciate gaming developers that use current and future technology and not make a game for 2005 capabilities (see also, the dreaded console ports).

Kinda like someone wanting their rotary phone to be Android capable. :)

Here is some information to help determine if you can run a 64-bit OS or not:

Granted, but most of us are still using 32-bit browsers (Chrome 64-bit for me, though) because as long as it "still works", people will still use them.

For everyday computing, 32-bit is still perfectly fine, for gaming it is not (and that is a good thing).

This is true, but if MS had made 64-bit starting with Vista, like they should have done, we wouldn't be in this situation. There is absolutely no reason to have 32-bit at this point. I could forgive MS delaying one generation as Vista completely changed the way hardware was handled and it took manufacturers a while to catch up. MS seen their mistake for not going 64-bit and when they had win7 beta, they required 64-bit for all drivers if they wanted windows certification (WHQL). But still they made 32-bit win7. win8 and win8.1 same thing. Now win10 beta has a 32-bit version? will will it end? Apple already went 64-bit a while ago.

/rant

Many people have been lumbered with the 32 bit version of Windows by their system builder of choice. For example my Windows 8 Tablet has the 32 bit version on it and there is no possibility to upgrade it due to the way it is done. This is a common issue on Laptops and even on some Desktops believe it or not.

This is false. I have upgraded many win8 32-bit systems to 64-bit. Win8 and UEFU BIOS has the product key coded in the BIOS . If you notice, you don't have a product key (CoA) on you system anymore. In fact, when you install the proper 64-bit version win8 knows it and automatically enters the product key and activates it for you. It's one of the new nice features.

If your MS won't support the OEM recovery system (posted above), then you should be able to call the OEM and they should have means to upgrade to 64-bit free of charge.

I'll repost the official Microsoft link from above.

Bad news, going from 32-bit to 64-bit will wipe everything off your computer. Make sure to backup everything beforehand, or your OEM may have a special bacup process built in.

This was going to be my rant as well, but I deleted a few sentences in previous posts. :)
They are still holding onto 32-bit version for... I have no idea.

However, since Vista was a mess anyway and people are still holding onto XP, I am pretty sure that making a 64-bit only OS (meaning, canning 32-bit compatibility as well) would have been great for Linux and the death blow for MS. It took Adobe until 2011 to make a 64-bit flash player for 64-bit browsers.

Zero reason, what so ever, to have a special 32-bit only OS on consumer level PC's. Period. If businesses want to by it OEM, go ahead (for really old programs), I get that.
The 64-bit OS can support 32-bit applications just fine, so why sell a 32-bit only OS?

Again, I have no idea, other than since they "can", they "will".

MS has a bad reputation of holding onto very, very old compatibility while pushing people to a touch screen phone UI on a desktop system. Seriously!!??!! LOL! :)

I was hoping that Win8 would kill 32-bit, but they wanted the "same" OS to run on phones and tablets, using a 32-bit CPU... /sigh. Same goes up to Win10 Tech Preview: They want the same OS everywhere and everywhere does not include killing past hardware and "forcing" tech advancements.

Ok, end rant for me, too, and trying to remember that this is a C:SL forum and not a general tech blog. :)

But, seriously, back at the OP, I would look into going to a 64-bit OS and backing up anything you cannot do without. You will be thankful in the future because Cities: Skylines is a great game.

Download Windows 10 tech preview, install on separated partition, install Steam - play!
Upgrade to full version when Windows 10 release.
Don't need to complicate things further, unless you really want to shell out $$$ now for Windows 7 / 8 upgrade...

I'm doing a 25 tile city, plus lots of assets. Process size was over 8GB last night - that's why there's no 32 bit version.

Wow! The largest I've seen is ~5.5GB but I haven't built a huge city yet. This is the first game that makes me feel like I need to upgrade from my current 8GB of RAM to 16GB - or more...
