Internet Explrer 8.0 uses the DEP/NX setting to stop ActiveX from running.If you have a problem running ActiveX you will need to tweak the Windows Registry.
This explanation of how to do this was kindly provided by Greg Lambert, technical director at ChangeBase:
Here is a sample registry keys that need to be configured to enable IE8 to download, install and configure ActiveX controls;
1) To over-ride download blocking in IE, you need to set the following registry key:
HKEY_LOCAL_MACHINE (or HKEY_CURRENT_USER)\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_RESTRICT_FILEDOWNLOAD\iexplore.exe= 0x00000001
2) To over-ride download blocking in IE, you need to set the following registry key:
3) HKEY_LOCAL_MACHINE (or HKEY_CURRENT_USER)\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_RESTRICT_FILEDOWNLOAD\explorer.exe= 0x00000001
4) To over-ride ActiveX Installations in IE8, you need to set the following registry key:
HKEY_LOCAL_MACHINE (or HKEY_CURRENT_USER)\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_RESTRICT_ACTIVEXINSTALL\iexplore.exe= 0x00000001
