They can be uninstalled just like any other program from Control Panel > Uninstall a program
 
Then login to your Affinity Store account, and download them from here: https://affinity.store/en-us/account/downloads/
 
Assuming that you've bought it online.

Both the Photo and Designer are very easy to use. You just have to understand the working of the tools in these software. As @Callum said, download the trial, watch the official tutorial videos from the staff and give it a shot. I'm sure you'll like it more and more as you use it.

Both the Photo and the Designer are excellent software. They can go toe-to-toe with Photoshop and Illustrator so why are these not more popular? I mean there are not many tutorials online (Not official, but by other people) and not many people know about them.
 
Now I know Photoshop and Illustrator are very old and that's also one of the main reasons they are so popular but I think people should know about Photo and Designer too. I mean all of these awesome features at just $39.99 each? What's there not to love about these two software?
 
I'd like to see more tutorials and videos about these two software online which explain how to achieve some complex photo manipulations and graphics designs like there are for PS and AI. I'm fairly new to the photo editing and vector designing world so I'd like to learn more. I've seen some spectacular photo manipulations and graphic designs online and I'd love to be able to do something on the same level some day.
 
May Affinity become as popular (Or even more) as Adobe :)

By popular I meant among content creators (Tutorial makers) as you can find a ton of tutorials for PS and AI (The factor is the presence of the software in the market). And I agree with you on the later points. And yeah, I also discovered the fact about upgrades after posting this by looking at this thread Upgrade Pricing Policy but I think it's fair :)

Tanujboy,
 
I too think that Affinity Designer and Photo are great products and I'd say that they are popular. While maybe not as well known as Adobe's offerings, Designer and Photo are popular. As with others who have posted before me, it takes time to become known let alone popular. To me, popular is difficult to quantify but I'm guessing that you mean with professionals. I do think that both Designer and Photo are making inroads with professionals but as you mentioned, Adobe has been around for a long time and their software is well entrenched in many markets with many professionals so it will take time to make inroads into the professional market. I hope that Serif continues to have push the envelope and that Designer and Photo continue to gain traction in the market because they are fantastic pieces of software. 
 
One important thing to note, you wrote that Designer and Photo cost $39.99 and have lifetime updates but that isn't quite right. I believe that the updates are only free between major versions. Upgrades to version 1 are free up to version 2. So if you are at 1.5 then 1.6, 1.7, etc are free but I think you have to pay an upgrade price at the next major version, which would be version 2. That is my understanding anyways. Maybe someone from the staff can clarify things?
