thanks for your answer. I completely agree that WinXP shouldn't be used 
in office setup anymore. However in industrial setups it is still a very 
common (perhaps the most common?) operating system. In this kind of 
industrial setup change of OS is very costly (you may need to change 
hardware, connectivity card, or even the whole CNC machine). Those 
system are obviously not connected to the internet... Actually seeing a 
MSDOS, a QNX or NT4 machine in factory is not that uncommon... With that 
in perspective WinXP seems modern :-)

CPython>3.4 is not compatible with WinXP anymore, and as it is more 
reliant on C code and on recent VCRedist, I guess there is not much hope 
on this side.

On the other hand PyPy is using vcredist2015 (which is still compatible 
with XP) and and is less reliant on C Code.

So I was wondering if there is any reasons for PyPy3.6 not to work on 
XP? If you think it is just a compile time issue, I'll be happy try to 
rebuild it on WinXP. If it has some more tricky issues, I'd be willing 
to spend some time / money on this.

The use case is for WAPT, a Software Deployment solution that use Python 
as its packaging scripting language.

Cheers,

Denis
