In the last version of dispcal, when I click options->install display device profile and choose the correct profile, I get that window where the I can preview the profile fine. But, when I click to install it, it loads the default uncalibrated profile. The only way to load the profile is by running the “dispcalGUI Profile Loader” exe. It seemed to work fine in version 22.214.171.124.
It is strange, the logs seem the same to me too. However, in 3.0.1 even though it previews the profile correctly and it says that it has been installed and activated when I click install profile, it just removes the current profile and leaves the screen unprofiled. It is visually obvious, as the screen turns blue.
It isn’t a huge bug as there are workarounds or I might just return to 3.0.0 version for now.
