After unzipping the download, clicked on the RT executable file and it works perfectly on my system, which is Win 10 Home (Single Language) Version 1709 (Build 16299.309).
I’m little bit confused.
You guys have just released RT 5.4: RawTherapee 5.4 released!
and at about the same time there is a ‘new build for testing’ 5.4?
This is an automated build that is cross-compiled and packaged using Travis CI, as opposed to the official builds that are natively compiled under Windows by some user.
However, we are still checking that the cross-compilation of RT under Linux using mingw-w64 produces executables that are as stable and as fast as those natively compiled under Windows.
Also, this build seems portable. Is it not? I copied the entire unzipped folder on a pen drive and it works well on another win 10 computer without any issues.
