HP officejet pro 7740, can not complete installation or setup utility

[Somerandomguy2]

I had to reinstall my 7740 after a reimaging. Everything worked 100% fine up until this point. I downloaded the complete 116 mb package and attempted to install the printer and utility once again and it will not complete. On the last step it makes me download the hp smart app and then tells me that my operating system is not supported. Things I have tried, delete driver, delete everything in print server, delete everything in program data. Nothing seems to work. This is seriously frustrating me as I am now without a printer or a scanner.

Here's what you need to do:

1. Uninstall HP printer software, and then remove the printer from your Devices list. 
2. right-click Start, search for "control panel" and open "Programs and Features"
   uninstall all HP printer software > via "Programs and Features"
3. right-click Start, search for "control panel" and open "Devices and Printers"
   In the "Devices and Printers" window look for your HP Printer. If you see it listed, right-click on it and choose "Delete" or "Remove Device.”
4. Restart the PC
5. Close all programs
6. download only this complete package: HP OfficeJet Pro 7740 Wide Format All-in-One Print and Scan Driver and Accessories 
   - Operating Systems: Windows 11
   - Release date: May 25, 2022
7. Close all programs
8. Open up the run command with the "Windows Key + R" key combo > in folder Downloads double-click on the EXE,
   File name: Full_Webpack-40.16.1234_1-OJ7740_Full_Webpack.exe (116.6 MB)
9. The installation was completed successfully, now you must ...
   - On the last step it makes me download the hp smart app < no, cancel or later
10. Restart the System again
11. Now the installation is complete.

Document error messages accurately, even better is to take a screenshot of it and upload here.
