No matter what I try I cannot change the default file type .ai to always open/be associated with Illustrator 2019.
The files always show up as blank icons and I have to now always right click and 'open with' and choose Illustrator 2019.
Bug with the new updated?
Madsih found the answer! One more tidbit though. It’s happening only in my windows 10 pro, but not windows 10 home
The solution provided does not work. I have tried changing the registry, tried assigning default in all the possible ways (including the version described here) and still it does not work. In fact now .ai files are struggling to open in Illustrator. This has only been happening since the 2019 update. There is most definitely a bug.
Neither worked for me. I had to download an old version. 😕
Here the same problem. It's a known issue in Microsoft. In fact, there is a similar tread of complains abut it in Microsoft community forums https://answers.microsoft.com/en-us/windows/forum/windows_10-files-winpc/cant-change-default-program...
It seems they are working on it... but you never know.
We are sorry we weren't able to find what you are looking for.
By the way... it says "Resolved"... but obviously isn't...
What worked for me is to just uninstall both Illustrator and XD and reinstall it.
This has been the only true fix for me. Feature update to Windows 10, version 1809. I can now associate file types with their programs again. .ai files were just the worst about it when the problem started happening. Get the 1809 Windows 10 update and your problems will be solved...
