As previous posting indicated - High Sierra was released in 2017 and Yosemite in 2014.


That or the user mis-typed Upgrade but really meant Downgrade ?


Either way and depending on the exact vintage of this MBP 2012 - it may qualify to run Catalina macOS 10.15 released 2019 or Mojave macOS 10.14 released in 2018


macOS Catalina 10.15 hardware requirements


macOS Mojave 10.14 hardware requirements



The Age of this computer will Govern what newer version of macOS it will Qualify to install. Use About this Mac from the Apple Icon on Desktop - the required Information will be there.


With the above information in-hand - follow this How to get old versions of macOS and verify what version this computer Qualifies to install.  For Best results use Safari to commence the download as Others may not work.


Safari will open a redirect and open the Apple Store where the download can commence.


Make Time Machine Backup  is very useful and can be used to Revert to Previous Working macOS


Notation - Mojave is the Last version to support 32 bit applications / extensions and Drivers. Catalina, Big Sur & Monterey supports only 64 bit and there is no workaround.


Suggest using Go64 to find 32 bit application before attempting the upGrade. Some or many of the Application already installed may required update or upGrades to 64 Bit Versions.
