Operation has been cancelled due to restrictions on my computer

Asked By 0 points N/A Posted on -

I'm running Windows 7 and I am having an issue with MS Office 2010. It won't open and it always throws an error.


This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.

This won't even work on clicking some hyperlinks in MS Outlook. How can I resolve this? I am the administrator of my own computer. I also searched for some solutions and they advice me to make Internet Explorer my default browser, which I already did but It still didn't work. Please help.

Yes, the first thing to try is to make your Internet Explorer as your default browser. Because this issue will occur if there is no default IE browser registered in your machine or you have recently uninstalled other browser. This is also due to a corrupt or missing file in your IE.

But if it didn't work, try to remember if you recently uninstalled any application which is associated to HTML open command or something like that. If this is the case, you need to alter the HTM/HTML association in your registry. To do this: (Backup your data before proceeding with this step)

1. Click Start> Run> Type Regedit in the text field and click OK. 

2. Navigate to: HKEY_CUURENT_USERSoftwareClasses.html  and then right-click its value and choose Modify.

3. Alter the value to htmlfile from ChromeHTML or FireFoxHTML.

You can also try to reset IE settings or make it as the default browser until the issue has been resolved. When using IE, go to Control Panel and then go to Internet Options. When using IE 6 or lower, this option is under the Programs tab. For IE 7, 8, 9, 10, this option is under the Advanced tab. If you are using Firefox, run the command: firefox -safe-mode firefox-safe-mode and then choose Reset all user preferences to Firefox defaults and then Make changes and Restart.

If it still didn't work for you, go to Microsoft website and click the Fix It button to automatically repair this issue.
