Operation cancelled restriction in effect (link)

Bravo Tomcat !
The spirit of your message is still valid today (May 29, 2009) because I've just had the same problem with Outlook, Excel, etc. In fact, it is indeed a program association problem with IE (Internet Explorer).
I am on Vista with the latest updates, Microsoft 2007, McAfee, IE8, etc. The problem is everywhere.
I am sharing the solution that I have just tested, which is very directly derived from Tomcat's:
In IE8, Menu "Tools" => line "Internet Options" => Tab "Programs" => Section "Internet Programs" click on the "Set Programs" button => Link "Set your default program settings and computer access"
There, check "Microsoft Windows" then click on the double arrow on the right to verify that the configuration is correct. If not, check "Customize" and select the appropriate buttons... (mainly indicate Internet Explorer instead of "Use the... current") => then click OK.
Exit IE and there, OH miracle, everything works again like before in all the software!
Good luck to everyone and thanks again to Tomcat, the true "Discoverer" of the "remedy" :-)))

1). Go to the link: http://www.dougknox.com/xp/file_assoc.htm

2). Download the HTM/HTML Associations (Restore the default associations for htm/html files).
3). Run the downloaded file which recreates a missing or corrupted registry key.
4). Restart your PC.

1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click on the following Registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\htmlfile\shell\open\command
3. Double-click on (Default).
4. In the Edit String dialog box, type "
C:\Program Files\Internet Explorer\iexplore.exe" -nohome,
and then click OK.

It was just a CAPS LOCK issue.

Hello, the problem is not with Internet Explorer.
Solution:
- Control Panel
- Programs and Features
- Microsoft Office
- Click on change and then repair
- Restart the computer.
Windows Vista configuration, Microsoft Office 2007
Best regards.

Hi,

I also had exactly this problem, but I wanted to open a link in Word. Now I no longer have it. How did I do it? Two things, but I don’t know which one worked:
- In Internet Options/Programs, I clicked on "Make default" to set IE as my default browser,
- and I also clicked on "Reset advanced settings" under Advanced,
- then closed all your Office pages, and reopened them and it should work. (to "restart" the program)

I think my problem occurred after trying another browser than IE and then uninstalling that browser (tested Google Chrome and Safari on XP).

(With Office 2007 and IE 7)

Hello, personally I had this problem after installing and uninstalling Chrome. I use Firefox on Windows 7 with Office 2007, to solve my problem I just had to go to Firefox: Tools -> Options -> Advanced, in the General tab at the bottom make sure Firefox is the default browser. Hoping this can help someone!

Hello everyone,

I have the same issue, and none of the tips provided above have resolved my problem. The message "This operation has been canceled due to restrictions in effect on this computer. Please contact your system administrator." continues to appear when I try to click on a hyperlink, or even on a link in the table of contents.

Configuration:
- Word 2007
- IE 7 (no possibility to perform the workaround proposed by Microsoft https://support.microsoft.com/fr-fr/help/307818/off-error-message-when-you-click-a-hyperlink-in-an-office-document this only works with version 5.5 of IE)
- My registry key HKEY_Local_Machine\Software\Classes\htmlfile\shell\open\command is present
- Kaspersky 7.0.0.124 with registry monitoring
- Windows XP SP2
- Firefox 2.0.0.14

It was working perfectly until now. The only recent change I made to my PC was installing version 3 of Firefox. But since I didn't like this new version, I uninstalled it and returned to version 2.0.0.14.

I thank in advance anyone who can provide me with a clear answer.

In IE7, you also need to go to Tools, Internet Options, and Programs, then choose the appropriate default programs; there are no options to restore the default settings.

SUPER !!!!
YOU ARE REALLY A GOD §
THANK YOU++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Hi,

I want to thank Sphinx from the bottom of my heart.

only user is not enough administrator

Hi

quick question, did you create the file??

because if the hyperlink was created by someone else and the link points to an address that is not on your PC.. that’s normal.

Hello,
To respond to "Claude"'s question given in the report:

Hello, the link http://www.dougknox.com/xp/file_assoc.htm is a dead link. 
Does anyone have another solution? Thank you

There is also the software RSTassociations.
