Can't install HP ENVY or ,NET Framework 4.6

[Ree5]

Just got the HP Envy Deskjet 3755.  Went to site for download and installation. Messages says must download and install .Net Framework 4.6.  Downloaded it, but it wont install.  Tried just plugging USB into computer.  Message that the printer does not support Windows 8.1.  Getting frustrated!

@Ree5,

Thank you for posting your query on HP Community,

Let's start off by running the Windows update troubleshooter.

Download and install the troubleshooter from this link.

Now try to perform Windows Updates - 

1) In the search box, type and open Windows Updates. 
2) Check for updates. 
3) If the updates are available, click on install and restart the computer. 

If the issue persists, I would suggest here is to download and install the .NET Framework 4.6.

For more details, please follow this link.

Now let's try to uninstall the printer driver from the root level and then install it by following the steps below: 

• Press “Windows key” + “r” to get the “Run” window.
• Type "services.msc" to get Services – Go to “Print spooler” – Right-click and “Stop” the service.
• Now again open "Run" - Type “spool” and ok - Go to PRINTERS folder - delete everything in that folder.
• Go to services again - Start the print spooler.
• Now check for issue resolution.
• If the issue persists, also try clean installing the printer drivers. Here are the steps:
• First, unplug the USB cable from the printer if present.
• Go to Control panel – Programs and feature – Select all the HP DeskJet printer entries and uninstall them.
• Now go to Control panel – Devices and printer – Select all the printer entries and remove the device.
• Press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" (There is a space between .exe & /) and press enter.
• Under print server properties, go to drivers - remove any entry there as well.
• Again, go to the Run window, type – “c:/programdata” – Go to Hewlett Packard folder, remove any printer related folders & files.
• Restart your computer.
• Please click here to download and install the software.
• Connect the USB cable if prompted and follow the on-screen instructions to complete the installation.
