Hi Guys,

The reason I raise the original is for all those configuration management tools which need the version number.

In the uninstall registry is very much an inconsistent.
*Anything with a Display Name in the registry (name in the GUI) will be listed.
* Their are two places for version information.
** 1 "large int (DWORD) version number" called "version" store across several integers in the registry, which supports <0-255>.<0-255>.<0-65535> this is not visible in the GUI.
** display version, which is a string, and can be set to anything, this is visible in the GUI.

"display version" is set most of the time.
"large int version number" not always

"large int (DWORD) version number" I have actual see software which as created this as a text string, which is just wrong. e.g. Google Chrome, however Google Update Helper does the right thing.

People see the "display version" so this needs to match the version of python.  I would expect most configuration management tools to use "display version" before "large int (DWORD) version number"

The following is based on installing python 3.6.2 (3.6.2150 not sure what this means)

display name should be "Python 3.6 (64-bit)" if you wish to encourage  only single version of 3.6 to be installed. or "Python 3.6.2 (64-bit)" if you wish to allow many versions of 3.6 to be installed. "3.6" matches closer to what happens in the unix/linux world (/usr/lib/python2.6).
 
display version string should 3.6.2 or 3.6.2.2150 never 3.6.2150 
"large int (DWORD) version number" should not be set, but you could force it to 3.6.2 given your unlikely to go higher than 255.255.65535 the automatic builds might not like doing this, might be easier not to set it.
