Dear Expert:

I have an installer which detects the installed version of Microsoft Office by looking at the registry entry HKEY_CLASSES_ROOT\Word.Application\CurVer.

It works well for Office 2000, XP, 2003 and 2007, and it works well even on Office 2010 over Windows Vista/7. But after installing Office 2010 Home and Small Business (the free trial version) over Windows XP SP3, this registry entry doesn't exists.

So my question is: How can I detect if Office 2010 (any version of it) is installed ?

Thank you in advance.

Did you search for winword.exe in your registry - If you don't find it somewhere - then Microsoft must be using some new method of installing their own software

I have solved this for my own. Some Microsoft Office versions, such as Microsoft Office Home and Small Business 2010 trial version, installs it as a "click and run" by default. This click and run creates a virtual application, which is isolated from the rest of the system, so automation doesn't work, and also some registry entries doesn't appear.

The solution is to Uninstall "click and run" and install Microsoft Office again as an MSI. More details on this article:

I found the solution for my own. After uninstalling "click and run" and installing Office as an MSI you can detect version just by you do on any office system:

Set obj = CreateObject ("Word.Application")
MsgBox("Version: " + obj.version)
