Deploying Win7 built Qt app in Win XP

Hello,

I need to deploy a Qt application in Win 7 and also in Win XP.
Is this possible? My Qt (4.6.something) and my app have been both compiled with VS 2005 in Win 7. Can I just copy the app together with the relevant Qt dlls to WinXP?

Thanks
Tom

Should not be a problem as long as you have not used any Windows 7 calls without checking the OS version first.

Yes, that's right. My app, developed in Win7 refused to run in XP, so I thought that there perhaps was some incompatibility, but now I traced the problem to a silly mixup of release and debug components. Now that I sorted that out, the app works in XP without problems.

Thanks
Tom
