Cannot open at revision

[Curtis Newton]

Hello,

Clicking on "Open Selected Version" gives an error

        Open file ..... failed with code -1 ...Application not found

but I cant find any setting to tell sourcetree where is my external editor

I tried custom actions, they just dont work at all, nothing happens when I click on them although I added one to use sublimetext with $FILE variable

I use windows 7 - 64

thanks

anyone ?
