In some cases, like malicious Word documents without VBA source code, you want to know which version of Office was used to create the VBA macros. Because compiled macros (VBA) don't run on all versions.

This information can be found inside the _VBA_PROJECT stream:

The 3rd and 4th bytes in this stream are a little endian word, whose value indicates the version of Office that was used to create the VBA code. This is all documented by Microsoft, except for the field values themselves.

Here is a list I compiled for different Office versions (Windows):

If you have other info for other versions, please post a comment or submit a sample.
