You can either check System.IntPtr.Size and see if it's 4 or 8 (which is what I've usually done in the past and works on all versions of .NET) or you can check System.Environment.Is64BitProcess (this will read a little better, but is new in .NET 4).

I am testing adodbapi with IPy 2.7.2a2 -- using my new laptop which I have set up as an everything in 64-bit test bed. My default test database is an .mdb (so-called ACCESS database) file. Microsoft has decided that the JET engine, which has historically been used to read and write that format is to be deprecated, so there is no 64 bit version of it. It is replaced by the Access Database Engine 2010 redistributable.<http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=13255> Of course, the new software requires a different connection string, one containing "Provider=Microsoft.ACE.OLEDB.12.0;". So, how can I tell which width of IronPython I am running, so I know which connection string to use? -- Vernon
