WinDev 12: How to identify Windows 64-bit / 32-bit ?

Hi,

the upcoming Windows 7 will require applications to find out whether they are going to be installed on a 64-bit or on a 32-bit system.

For myself, I want to offer the same application in 64/32-bit versions for download. How is it possible to stop the user from downloading a 64-bit version and installing it on a 32-bit Windows?

1 - How can I identify the 32/64 versions of Windows (XP, Vista, 7, 2008 ..) from a running WinDev-application ?

2 - How can the application know whether it was compiled for 32-bit or 64-bit?

Kind regards,
Guenter

Hi Guenter,

is exeinfo() what you are searching for ?

Hi again,

for question 1:

does syswindowsversion(sysversioninfo) give different results?
I cannot test it because lack of a 64 Bit System.

Hi Erik,

yes, thank you! Indeed, ExeInfo() tells the mode of the exe file - 32/64 bits !

However, SysWindowsVersion() does not tell the difference between a 32-bit / 64-bit Windows. It just says: Vista, XP .. but as I've seen, there is a system integer data type and that is 4 bytes in length for Windows 32-bit and 8 bytes in length for all Windows 64-bit OS. I just have to find out the length of a system integer ..

Ok, that's solved, thank you!

All the Best to You and Your Familiy !
Happy New Year!
