How to roll back SR5 to SR4 in Rhino V7

Does any body know how to roll back Service Release 5 to the previous version SR4 of Rhino 7 ??
I’m working in a project using ShapeDiver plugin for Grasshopper and my Rhino 7 auto-updated into SR5 a few days ago (Rhino 7 SR5 2021-4-10 ( 7.5.21100.03001 )).

Now my system is acting unstable when uploading GH definitions to the ShapeDiver’s platform in the cloud. Note: ShapeDiver is right now in beta stage supporting Rhino 7.

Before the update it was working fine, therefore I just need to go back to SR4.

I really appreciate any help on this,
Thanks

Hello - you may be able to find the 7.4 installer by rummaging around in the folders here:
C:\ProgramData\McNeel\McNeelUpdate\DownloadCache

Pascal thank you so much! I found the 7.4 installer ! I really appreciate your help!
I’m sure it will work fine, but before completing I have only two more questions:

1- How can I backup all my rhino settings and menus layout before executing the 7.4 installer?
2- The 7.4 installer displays the following options, which one do you recommend ? (see image)

Thank you !
