The whole .exe vs. .msi thing really isn’t an issue. It worked the same way back in Version 2, and it’s intentional. You just need to know which one you installed. The only tricky part is that the download page labels them in a slightly confusing way, which can mislead a lot of people. But the moment you actually download the file, you can clearly see whether it’s an .exe or not.
Many who used all three Affinity apps before were already switching between them inside a document. With Affinity Studio, that workflow has become even smoother. And the software keeps growing and improving. That’s why moving to Version 3 makes sense in the long run.
If you want to make the transition easier, check out some Affinity Studio tutorials on YouTube. You’ll get comfortable with the new setup much faster than you might expect.
