2. Restart the PC
3. Close all programs
4. download only this complete package: HP ENVY 4520 series Print and Scan Driver and Accessories 
5. Close all programs
6. Open up the run command with the "Windows Key + R" key combo > in folder Downloads double-click on the EXE,
   File name: Full_Webpack-40.15.1230-EN4520_Full_Webpack.exe (148.3 MB)
7. The installation was completed successfully, now you must ...
8. Restart the System again
