Based on @Konstrukto’s report, I have just unpacked the file “krita-x64-5.2.0-setup.exe” and can confirm that the file “FFmpeg.exe” is missing in it. In the archive of the portable version, however, the file “FFmpeg.exe” is present. Since I myself only work with portable versions of Krita, I didn’t notice this, and I hadn’t explored the absence of the “FFmpeg.exe” file more deeply with @Konstrukto, during the RC phase, for some unknown reason.
I just have reported it as bug:
@Konstrukto, can you please confirm this bug in the bug-tracker?

Add/Edit: The fixed file is now downloadable via Krita’s homepage and as well from Jenkins.
