Thanks so much for this, you fixed my G3

Thank you!

Excellent !!! It works

Mate you are da man... all i did was go into control alt delete, task manager, found hp print scan doctor and hit end process and then dell power manager let me perform the update. thank you for the great tip

This solution worked liked a charm. I stopped the HP Print and Scan Doctor Service from the Services console and tried again to install the 3.9.0 version of Dell Power Manager and it worked immediately.

The app is working as usual now. 

Thank you!

Helped! Thanks for the solution

Thank you very, very much, your post saved me a lot of time. Disabling the HP Doctor service did the trick for me.

Thank you a lot man!! You are THE MAN! Shame on the Dell support team...

This solution worked perfectly for me. I had the similar issue with installing dell power manager and disabling my HP Print Scan Doctor Service worked!  Thanks!!

Thank you,  your solution worked for me.  By ending the task HP Print and Scan Doctor, I was able to complete the installation/updating of the Dell Power Manager Service.  No more Error 1720

do you have to disable the service every time we boot up?

If you disable the service it should stay disabled.  A software update may cause it do become reactivated but other than that it should stay off.  If you just stop it, it will restart upon reboot.

I was having the same 1720 error message pop up. I quickly read your post and then stopped and disabled the same HP service and it fixed my error issues with Dell Power Manager Update installation.

Thanks!

Nicely done and thank you!  Had the exact same situation.  Disabled HP Scan Doctor and life was good again.

Thanks for all the effort to find a solution to this problem and to explain it here. I was finally able to install the dell power manager services again on my Dell XPS 15 9570. It was a really big help!
