When clicking on a hyperlink in an e-mail, I get this Message : “This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.” I get this message every time that I attempt to use the hyperlink. I am the administrator on this stand alone computer. How do I deactivate this feature so that I activate hyperlinks ?
Good answer:
If you received this error after uninstalling any application that takes over the HTML open command (including, but not limited to, Chrome & Firefox browsers) you may also need to change the HTM/HTML association in the registry.
Start, click Run, type Regedit in the Open box, and then click OK.
Browse to HKEY_CURRENT_USER\Software\Classes\.html
Right click the value for the .html key and select Modify…
Change the value from “ChromeHTML” to “htmlfile” (or from FireFoxHTML to htmlfile)
Repeat these steps for htm and .shtml keys if they exist. You may also want to check the xhtml and xhtm keys.
