I'm also running Win7 sp1 offline for the same reason. Since post winxp SP1 the operating system works against the user as if Microsoft knows better about how I want to run it. I consider it as malware to be contained. I have the same opinion about cell phones, (mandatory at my work :( , turn it off at home and don't do anything personal on it).
Your thread made me check those again because I've been able to install it before. No problem installing two versions of vc++ 2015 update 3 downloaded on MS website, see picture. Dolphin 5.0 emulator that requires it runs ok. Those redists install very slowly though, 20 minutes each and seems to be jammed for a few minutes at first.
When I searched for your error, I found the following comments on a youtube video:
""
From the Control Panel>Windows Update, I hit "Change Settings" and clicked
"Never check for updates."

(This is always the case with me since I run offline, I do the same with defender but leave the firewall on. Perhaps this is why it installs on my setup?)
Also these could help:

-Hello :) I'm gonna tell you how I fixed this on Windows 7 Home Premium.
First uninstall all of your Visual C++ by going to control panel > programs
and then just uninstall everything that got "Visual C++" in it's name.
Restart PC. Click start. Type in "CMD". Right click "CMD" and run it as admin.
type in (WITHOUT quotation marks) "net stop wuauserv". You can close cmd now.
Install vc_redist.x64 and vc_redist.x86 (It should not be stuck on installation,
since we blocked WindowsUpdate service by cmd).

-finally figured out how to get this to work on win 8.1 so frustrating.
first thing you're going to want to do is uninstall visual c++ 2015 completely
restart your computer. and then go to control panel go to all control panel
items go to Windows update in the control panel go to change settings and then
enable never check for updates. restart your computer and then go to this website

NovumZ: Abzu offline installer had mendatory vc redist 2015 even! (Please undo this Change Kindly GOG.)
That caught my eye! -it used to come in a separate install window; that way you could stop another multiple redist 2015 from installing 20 times on top of another and would be hard to see other installed programs I monitor.
You mean it force install the redistributable and no checkbox is available? hah, Dolphin 5.0 had a checkbox for this...
Hope I won't have problems If I ever decide to buy it.
