Question

I have setup spell checking through WinWord but I need to find a way to in sure that Word 2007 is installed on there systems.

I have seen the Registry Versions of this but I also read that it can provide false positives. So I am in the ‘market’ as it were to figure out how to accomplish this. Can it be as simple as doing a File.Exists() on WinWord.exe in the 2007 file path?

Any other ideas?

Answer 1

Type word = Type.GetTypeFromProgID("Word.Application");
if (word != null) {
    // Word is installed
}

To check that Word 2007 in particular is installed:

Type word = Type.GetTypeFromProgID("Word.Application.12");
if (word != null) {
    // Word 2007 is installed
}
