HKEY_LOCAL_MACHINE\Software\Autodesk\AutoCAD\R19.1\ACAD-D001:409 What is ACAD-D001:409?
R19.1 is the release number, the this corresponds to AutoCAD 2014
These digits like D000:409 are a ProductID (D000) and a LocaleID (409).
The ProductID structure is a 4-digit value. However, prior to AutoCAD 2006, the ProductID structure was only 3-digits with a single [p] value. Due to the number of products based on AutoCAD, in AutoCAD 2006 structure was changed to 4-digits.
[n] = Number representing AutoCAD base release (see below)
[r] = Release number within AutoCAD base, reset to zero for every new n
[pp] = Product based on AutoCAD (see below)
ProductID Assignments (Assigned [n] Values)
D = AutoCAD
B = AutoCAD
A = AutoCAD
