Is there any solution to know if the running app is x86 or x64 ?

Hi,

> Anyway, I'll have to run the app to know if it's a 32 or 64 bit application...

Ages ago I used this code to get executable bitness using AutomatedBuildStudio - another fantastic tool by SmartBear that has been discontinued for some reason... 😞

I hope that you will be able to port it to the language that your test project is based on.
