Backup and Restore

Hello,
Today, while opening a pdf file I got a popup message about an update to acrobat reader, I pushed the "yes"
button and it started a long download and a long install, while the process running I managed to see some changes, even to the registry. When finished, I opened the pdf file again, I saw the new version (DC something) - it does not suit me. I searched and downloaded the acrobat reader
11 "AdbeRdr11010_en_US.exe" file just in case I have to reinstall it.

Now here is my question:
1) Uninstall the program using the "uninstall programs" and reinstall with the downloaded file, or
2) Restore the system with a restore point made 3 days ago, I checked which programs will be affected,
only this acrobat reader and one firefox update.
Answer will be appreciated.
Thanks

Hello,
Thanks WHS,
Could not make a restore as you suggested, I tried twice (remembered to disable the antivirus) and got an
error, attached screenshot. Then I used the uninstall option, made some manual 'cleaning' and reinstalled
from the downloaded file, now it works.
Later I will do some investigation, check the disk and look what is the error.
If you have something to add, please do.
Thanks
