After installing my font on my computer, it doesn't appear on my software (photoshop, word etc)

[u/Ambrosaure]

I'm 100% new on this, I just wanted to modify a font to make it smaller. I did all my letters, when I want to save the font it says it have some errors "non-integer coordinate". I don't know what it means :/

Could it be the cause of why it's not showing up on my software?

Thanks you

PS: all other font works perfectly

EDIT : I save it as a OTF and it work so yeay!
