[Cura 3.0.3 won't open]

I recommend deleting everything you ever saved in cura.  It should all be in %appdata%/cura.  Then when you re-launch 3.0.3 it will create those folders fresh.

When you say everything... what exactly? Like which folder to delete? Thanks!

*EDIT*

Found what you meant but sadly no change. I will re-download 2.7 and run it (if it crashes I'll soft reset it) and I'll edit this post again

*EDIT after running 2.7*

So 2.7 now works; I deleted the roaming data folder

*EDIT after running 3.0 again*

And now it works.... AWESOME! Thanks so much!

[Cura 3.0.3 won't open]

Hello @Printers_Unite, you said that this problem happens with Cura 2.7 and Cura 3.0.

Can you tell me what printers (and their configuration) do you have in 2.6?

Alternatively, do you still happen to have your two cura folders in \AppData\Local and in \AppData\Roaming? If you won't mind, you can upload them so that I can take a look at the configuration you have and then check why Cura does not launch for you at all.

Yea so it works with 2.6 perfectly fine. I do have all three folders! I have a custom profile for my CR-10. How do I upload it?

Right so this is a little inconvenient due to the brand new release of the slicer but still (this happened with 2.7 as well);

Everytime I try to open the software, it launches the loading stuff but, when it finished loading machines, it closes. It doesn't even register as an open application (I opened it and then went onto task manager and it didn't appear). I reinstalled 2.6 (because that was the last one that worked with me) and after it loaded machines, it open the software straight away; no problem opening it.

I opened the software through admin and I've reinstalled it a few times; I've also gone to the file location and opened it directly there.

I'm not an advance programmer (Nor one at all) so if you do try to help (thanks in advance) please use simple english ahah

Thanks!
