Project 10 is expected to be the last formal project of varocarbas.com. I will continue using this site as my main self-promotional R&D-focused online resource, but by relying on other more adequate formats like domain ranking.
Note that the last versions of all the successfully completed projects (5 to 10) will always be available.

CoreRun.exe is not constrained by the Windows version, other than by the fact of having to be 64-bit (and including a supported .NET version, as discussed in the next section); at least, this is the case with the tested Windows 8 and 10. Nevertheless and as explained in the previous section, it should be noted that I didn't perform a detailed analysis of the source code.

At a first sight, converting the target platform of the CoreRun.exe source code into 32-bit seems acceptable (i.e., simple enough to comply with the "only threat if no relevant modifications are required" idea which underlies this whole project), but such an assumption doesn't hold. Although there is a functional Visual Studio project, it has many external dependencies which would also need to be adapted (i.e., relevant number of errors when changing the target platform from 64-bit to 32-bit).

Although creating a 32-bit version of CoreRun.exe isn't trivial, assuming that it will be exclusively used on 64-bit OSs no matter what would also be disproportionate. This 32-/64-bit differentiation represents one of the multiple layers of complexity which decrease the likelihood of CoreRun.exe being a real threat: the more constrained its usage conditions, the less likely to be something about which to worry.
