@PrachandPratap, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
I understand you're encountering an error message:
"A problem occurred while preparing to install software on your system"
while trying to install the driver for your HP LaserJet Pro MFP 126nw on Windows 10 (64-bit).

Let’s walk through some steps to resolve this:

Uninstall Previous Driver Attempts

1. Press Windows + R, type appwiz.cpl, and press Enter.
2. Look for any HP LaserJet 126nw software or drivers.
3. Right-click and Uninstall them.
4. Restart your PC.

Download the Full Feature Software

Instead of using Windows Update or CD, download the latest driver directly from HP:

Install in Compatibility Mode (if error persists)

3. Check Run this program in compatibility mode for: and choose Windows 8.
4. Click Apply and then OK.
5. Run the installer again.

Temporarily Disable Antivirus/Firewall

Sometimes, security software can block installations.

• Temporarily disable any third-party antivirus or firewall.

I hope this helps.
