install OS X 10.9.4 Mavericks on an old MacBook Air

How would I go about installing OS X 10.9.4 Mavericks on an old MacBook Air please?

the Mac currently has Mountain Lion, but I can't run certain apps such as dropbox.

I don't want to upgrade to High Sierra. The old MacBook is slow enough as it is.

Official System Requirements

On June 10, 2013, Apple didn't yet publicly note which Macs are compatible or the minimum system requirements for the operating system, but AppleInsider first broke unofficial compatibility information for the Preview Release citing an unnamed loose-lipped developer.

On October 22, 2013, Apple shipped OS X Mavericks and the final release offers the same compatibility as the Preview Release.

Specifically, these Mac categories are supported:

iMac (Mid-2007 to Mid-2014)
MacBook (13" Late 2008 Aluminum, Early 2009 to Mid-2010)
MacBook Pro (13" Mid-2009 to Mid-2014)
MacBook Pro (15" Mid/Late 2007 to Mid-2014)
MacBook Pro (17" Late 2007 to Late 2011)
MacBook Air (Late 2008 to Early 2014)
Mac mini (Early 2009 to Late 2012)
Mac Pro (Early 2008 to Late 2013)
Xserve (Early 2009)

So, check your Mac production date (Should be on sticker or if you don't heva this information just put your serial number to google and it will comes up with version).

Thanks :Tom Cieslik.

Indeed my MacBook Air IS supported. My question is: HOW DO I INSTALL MAVERICKS.

i.e. in the app store it wants me to upgrade for free to high sierra.

please, just where do I go to download and install Mavericks. Thanks.

Thanks Tom, but again.... this isn't what I need. Notice what this is:

The OS X Mavericks 10.9.5 update is recommended for all Mavericks users.

this is merely a 20MB update for EXISTING Mavericks users. My Mac doesn't have Mavericks to begin with. It has Mountain Lion. I need the ENTIRE Mavericks install. Not simply an "update" for Mavericks users.

Direct update is not available.
You will need to upgrade your Snow Leopard system to 10.6.6 (10.6.8 would be better) so that you have Applications -> App Store.
If you have previously downloaded Mavericks, then you should be able to download it again via Applications -> App Store -> Purchased tab
If you never downloaded Mavericks, then it is NOT available for new downloads.  In this case the only option is to make a Genius Bar appointment at your local Apple store and ask them to install Mavericks for you (this may or may not work).

Otherwise, you can download Yosemite again or go to Sierra.  Actually since you are running Snow Leopard, you can download El Capitan
To the best of my knowledge, those are your options.

Per both my comments above, I'm running Moutain Lion. NOT SNOW LEOPARD. Therefore, yes I have the app store. I'll check that.

I know what you have and I understand, but Like I said You can't upgrade to Maveric from Mountain Lion. It's not available anymore.
Try to upgrade to Snow Leopard first or go to straight for El Captain
