Reading PDF metadata: problems with PDFVersion(Acrobat 3x), any workarounds with VB6?

When Acrobat Pro 6 is installed, the following VB 6 code works well

Dim oPDF As Object
Set oPDF = CreateObject("AcroExch.PDDoc")
oPDF.Open (PathtoMyfile)
sFileTitle = oPDF.GetInfo("Title")

However, when this code encounters a PDF file with PDFVersion(Acrobat3.x) it hangs and eventually crashes.

Please can an expert suggest a workaround, such as a trap to detect the version before the hang/crash, or better yet, of course, a way to read the metadata of the legacy version?

I'm encountering more and more pdfs that are five or more years old, so the problem of the version of Acrobat used to create them is getting quite urgent. I've increased the points accordingly.

Suggestions will be gratefully received

I'm narrowing down the problem, which may help explain my question better.
On a machine with Acrobat Professional I can read the title of a pdf using this code

Dim oPDF As Object
Set oPDF = CreateObject("AcroExch.PDDoc")
oPDF.Open (PathtoMyfile)
sFileTitle = oPDF.GetInfo("Title")

What should I subtitue for "Title" in GetInfo to read the PDF version?
In the dcoument properties (accessed from File > Properties), for a problem PDF, typically the data is

PDF Version: 1.2(Acrobat 3.x)

I've tried various abbreviations of "PDF Version" without succes. Help would be really appreciated, please
