Can't restore Smart app for Envy Pro 6455 printer setup. I've tried uninstalling but it won't let me restore. Microsoft just keeps giving me an error message, virtual assistant no help. Any ideas for what to try next ?

Welcome to the HP Community Forum.

Unfortunately, a vague error message is generally useful only in the context of what is happening at the very spot at which a program fails to move forward. 

If the HP Smart application were still installed in Settings > Apps > Apps and Features, you could try the Reset option in the application.  The Reset does a few things, one of which is that it removes the user data from the app -- this can be useful if the application user data gets tangled and stuck in the app.

What next?

We cannot really fix the Store -- and, at the moment, the Store is the only source to get the HP Smart application for Windows.

I can offer the following...

You could try using System Restore to "go back in time" to an earlier date when the app still worked.

Of course, to use System Restore requires that you have a usable Restore Point.

Meh.  Might work -- it can be a "temporary" fix when the source of the problem is in the File System or comes back after Windows Updates are applied.

What else?

Restart Everything, including the router that controls your network

and

Disconnect from Virtual Private Network (VPN) connection before downloading.

Next,

Windows 10 – Windows 11
