Looking for instalator DaVinci studio version 15.0b3

Hi,
I'm urgently looking for a Resolve studio version 15.0b3 installator.
I need this version because in other versions I have bad corrections and I have no longer installer for this version
Can someone help me please?

Thanks
Miroslav Bláha

Go to this page where you will find the downloads, and scroll down the list to the version you want.https://www.blackmagicdesign.com/support/family/davinci-resolve-and-fusion

Hi,
I need Beta version (it was public beta 15.03b) and Blackmagic has delete these versions from the support site

in other versions I have bad corrections

What does that mean? "Corrections" implies color work, but the database used will be the same. Installing an older version won't change the work done to the project.

The database is ok. But there must be some change in Color space transform plugin between version 15beta and version 15.0
In version 15.0 and later (15.1, 15.2) was output degraded with some strange artifacts.
Finally I found on the Internet v15.0b2 installer and then I have successfully exported my work

I have the DaVinci_Resolve_Studio_15.0b3_Mac.dmg installer.
