Hey there,
updating to version 1.0.0.2075 resulted in Windows Defender flagging the executable file als malicious. I do have the software installed in the %appdata% folder environment. So, I am aware of possible false positives.

However, this did not happen with a prior version. So I uploaded the file to virustotal resulting in 11 out of 71 "positives". Also, the EXE-file is shortened to 8.3 naming convention this time (named COLOUR~1.exe"), instead of ColourSpaceZRO.exe (like it was before).

False positive or something wrong here?

Please see the included 'Installation' PDF within the download, as well as the Sticky thread in this forum.
That is yet another False Positive, as your 11 out of 71 positives shows.
The change to the .exe name is likely caused by the AV software, preventing it from running.
