HP ENVY 7645 printer

Running on Windows 7
The printer works fine until I have to print in a diff program, Example I'm printing in Word and then I go to Excel or maybe on-line I cannot print I have to restart the printer. In Event Viewer I do see:

Activation context generation failed for "C:\Program Files\HP\HP ENVY 7640 series\DriverStore\Yeti\V3\amd64\hpinkinsDC11.exe". Dependent Assembly Microsoft.Windows.Common-Controls,language="*",processorArchitecture="amd64",publicKeyToken="6595b64144ccf1df",type="win32",version="6.0.0.0" could not be found. Please use sxstrace.exe for detailed diagnosis.

Any suggestions?

Disk cleanup in Windows 10
Use the System File Checker tool to repair missing or corrupted system files. It is always a good idea to back up your data before proceeding.
System file check (SFC) Scan and Repair System Files & DISM to fix things SFC cannot.
Perform Clean Boot in Windows 10 / 8 / 7
Afterwards try installing the software again.

Good Evening,

The error seems to be related to corrupt installation of the HP Software. I would encourage that you reinstall/uninstall and then reinstall the HP Software for this printer. Once you have done this, your printer shall work fine across all softwares.

Thank you and have a nice evening,

Scan your system with Malwarebytes or a decent Antivirus,  it sounds like your PC is Infected.
when finished, reinstall Printer driver if needed.
