determining the installed version of internet explorer

if your application requires internet explorer services, you must determine the version of internet explorer installed on the local system before installing your application. there are two methods that can be used to determine the installed version of internet explorer. the first obtains the version information from the registry, and the second obtains the version information from one of the internet explorer components.

determining the internet explorer version from the registry

to obtain the installed internet explorer version from the registry, open the following registry key:

hkey_local_machine\ 
   software\ 
      microsoft\ 
         internet explorer

in this key, obtain the version value. this is a string value that contains the internet explorer version in the following format:

"<major version>.<minor version>.<build number>.<sub-build number>"

additionally, this registry key contains a build value, a five-character entry that takes the following format:

"<major version><build number>"

the following are the versions of internet explorer and the version and build values they return.

determining the internet explorer version from shdocvw.dll
