Since this post is under iPhone apps, this only applies to iOS. Also, your post is not clear. If you mean installing the current WhatsApp on older iOS, sometimes the current version of an app, not just WhatsApp, will not support an older iOS.

Simply turn on your Wi-Fi or data connection on your mobile (we suggest the use of Wi-Fi only since using Data can incur you a lot of charges specially when downloading stuffs) and connect to the internet. Open the Play Store app and search for the WhatsApp application.
App Pc

1. Download the WhatsApp file in your browser.
2. Make sure your tablet has the setting to install apps from unknown sources.
3. Install the app.
4. Provide all the necessary details.
5. Verify your phone number.
6. Start using the app.

App Pc

Not, unless your PC is a phone.
Whatsapp is a (smart)mobile phone messenger that uses the phone number as the account name.
There are not even apps for tablets to use whatsApp, because they also don't have a phone number.
