Learn how to fix when you get "Windows could not start the Software Protection service. Access is denied" error while starting Software Protection service.

While performing various operations, Windows requires dependency upon background services. For example, when you’re installing new software, the Software Protection service checks whether software is from reliable source or not, Windows is activated or not while installing this software etc. If this service found something that is not legitimate, it won’t allow you to install new tools your machine.

Recently, while using Microsoft Office on a system, I received following error:

Microsoft Office can’t find your license for this application. A repair attempt was unsuccessful or was cancelled. Microsoft Office will exit now.

This kind of issues may come into play if Software Protection service is not running or it is having trouble to get triggered. So in the Services (run services.msc command to get this) window, I found that Software Protection service wasn’t running.

When I tried to start this service, I come around another error then:

Windows could not start the Software Protection service on Local Computer.

Error 5: Access is denied.

From the Access is denied in the message, it’s clear that some permissions hiccup is causing this issue. If you’re too facing this problem, I suggest you to first make sure that Windows is activated on your system.

FIX 2 : Windows Could Not Start The Software Protection Service On Local Computer

NOTE : Making mistakes while manipulating registry could affect your system adversely. So be careful while editing registry entries, also its better to create a System Restore point before proceeding.

1. Press W8K + R and put regedit in Run dialog box to open Registry Editor (if you’re not familiar with Registry Editor, then click here). Click OK.

RegistryEditor

2. In the left pane of Registry Editor, navigate here:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform

3. In the above shown window, right click SoftwareProtectionPlatform key and select Permissions. In the Permissions window, highlight sppsvc in Group or user names section. Now check the options against Full Control and Read for Allow in Permissions for sppsvc section.

Click Apply followed by OK. You can now close the Registry Editor and reboot the machine. After restarting the system, you’ll find that problem no longer exists.

Hope this helps! If you’re not able to start Bluetooth support service, go here.
