Posts Tagged ‘Hyperlink’

You receive the following error when you click a hyperlink in Outlook (2003, 2007, 2010)

Error: This operation has been cancelled due to restrictions in effect on this computer

This is possibly due – default browser setup, registry corruption or file association

Step 1
Before I start with possible causes and solutions that I have encountered, please do the following:

1) Create a System Restore point

2) Backup your registry completely
3) Backup user preferences and data for IE and Chrome/Firefox (if any); plugins or add-ons (if any)

This is for precaution only, I have not encountered any issues.

Step 2
Cause 1 – This issue may come up if the default browser is changed from Internet Explorer to either chrome or firefox.

Solution – This issue is known to Microsoft and so they allow you to fix this issue automatically or manually using this link:

Cause 2 – After upgrading to a newer version of Microsoft Internet Explorer the following registry key may either missing or corrupted:

HKEY_Local_Machine\Software\Classes\htmlfile\shell\open\command

Solution – This issue is known to Microsoft and so they allow you to fix this issue automatically or manually using this link:

Microsoft suggests that you either reset IE settings and manually set IE as default browser OR import the following registry key from a different computer which is working fine

HKEY_LOCAL_MACHINE\Software\Classes\htmlfile\shell\open\command

Step 3
It is important to verify that “HKEY_CLASSES_ROOT \.html” key is “htmlfile” and not “ChromeHTML” or “FireFoxHTML”

Step 4
If the doing the above still does not help, then uninstall Google Chrome and/or Firefox completely. You can re-install them later.

To remove Chrome or Firefox using “Add/remove Programs” in XP or “Programs and Features” in Vista/7 under control panel is one way to go.

To manually and completely remove Chrome; make sure that you un-hide file extensions. Backup your registry as I am going to suggest editing the registry and incorrect modification to registry can cause system damage.

Download the “chrome_remove.reg” file from here, rename it to “remove.reg” and run it.

Then;
For Windows XP; go to C:\Documents and Settings\USERPROFILE\Local Settings\Application Data\Google
For Windows 7; go to C:\Users\USERPROFILE\AppData\Local\Google

Right-click the Chrome folder and Delete it.

To manually and completely remove Firefox; first using “Add/Remove Programs” in XP or “Programs and Features” in Vista/7 under control panel to uninstall the application.

Then;
Delete Firefox installation folder under C:\Program Files\Mozilla Firefox or C:\Programs Files (x86)\Mozilla Firefox

Then;
For Windows XP; delete C:\Documents and Settings\USERPROFILE\Local Settings\Application Data\Mozilla\Firefox
For Windows 7; delete C:\Users\USERPROFILE\AppData\Local\Mozilla\Firefox

Then;
Download the “firefox_remove.reg” file from here, rename it to “remove.reg”  and run it or simply locate the following entries in registry and delete them:

HKEY_CLASSES_ROOT\FirefoxHTML
HKEY_CURRENT_USER\Software\Mozilla
HKEY_CURRENT_USER\Software\MozillaPlugins
HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla
HKEY_LOCAL_MACHINE\SOFTWARE\MozillaPlugins

Step 5
Rebooting your computer would be a good thing to do after uninstalling the other browsers and registry change. Check if hyperlinks work now.

Step 6a – Windows XP
Finally if there is still an issue, you can download the html association fix registry file here and run it. This is specifically for Windows XP. This will reset all the registry associations for default browser to IE and original state.

This registry fix has been tested by me and I did not find any issues with it.

Step 6b – Windows 7
Finally if there is still an issue, you can download the html association fix registry file from here and run it. This is specifically for Windows 7. This will reset all the registry associations for default browser to IE and original state.

This registry fix has NOT been tested by me.

Step 7
Reboot your computer and test.

Conclusion

I have tested all the steps except for Step 5 (my issue was chrome related) and Step 6b. Please read through completely and most importantly follow Step 1 and backup.
