This is the first time I came across this one, a client of mine was receiving the error “This operation has been cancelled due to restrictions in effect on this computer” when they clicked on a Hyperlink in an e-mail. At first I thought about Group Policy, but since it would have been me that would have to had set it I quickly ruled this out. The client did indicate that this only started since a failed attempt to install Google Chrome on the PC in question.
I reset Internet Explorer 8 back to its default settings and removed both Chrome and FireFox from the PC. This had no affect even though a few forums indicated some success with this method. It turns out that a registry setting is at fault, the “HKEY_CURRENT_USER\Software\Classes\.html” key to be specific.
- If you open regedit and browse to HKEY_CURRENT_USER\Software\Classes\.html
- In the right pane right click on the Default Value and select Modify
- Replace whatever value is there with “htmlfile”.
- Also check HKEY_CURRENT_USER\Software\Classes\.htm
HKEY_CURRENT_USER\Software\Classes\.shtml
HKEY_CURRENT_USER\Software\Classes\.xhtml
HKEY_CURRENT_USER\Software\Classes\.xhtm
Restart the PC and the issue should be solved
