This short guide explains why there are different version formats for Corona in various places.
The most "official" version format is 14.11.626144 - this is what we use on the Chaos download page and what we use internally when developing Corona.
What you see in the file properties of the installer executable and some Corona DLLs in Windows is 14.11.62.6144 - this is because the version components are limited to 4 16-bit numbers in Windows, so each component can only be in the 0-65535 range. So in order to get the pipeline number there, e.g. 626144, it is split into 3rd and 4th as 62.6144. This cannot be made consistent with the 14.11.626144 version format simply because it's a Windows limitation.
The registry value 14.11.0.626144 is what is used by the Chaos installer - it expects one extra component that we don't use, so the 3rd number is always zero.
We could in theory use a single, unified version format, however that would be risky due to various limitations.
