Outlook 2007 URL hyperlinks opening in Internet Explorer 64bit instead of 32bit.

Hi All,

I have a programme that uses a 32bit active x component and when I receive an email that has a URL needs this activex component it opens in 64bit IE instead.  Even though I've defaulted my applications to use IE and pointed it to the 32bit exe.

Is there a way to force Outlook to use the 32bit IE install?

Thanking you all in advance.

Hi,

Does the program call the CoCreateInstance function to create a 32-bit instance of Internet Explorer? If this is the case, please check if the following KB article applies:

https://support.microsoft.com/en-us/kb/2310259

This issue occurs because no 32-bit handler for the InternetExplorerMedium class identifier (CLSID) is registered. 

An application calls the CoCreateInstance function to create a 32-bit instance of Internet Explorer 8 in a 64-bit version of Windows 7 or of Windows Server 2008 R2. This operation fails when there is no 32-bit handler for the InternetExplorerMedium CLSID in the running operating system.  In this scenario, the CoCreateInstance function creates a 64-bit instance instead.

Since this question is more related to Internet Explorer, if you need further assistance on the issue, I'd recommend you post a new question to the forum for Internet Explorer:
