Labview 32bitDLL not loading in non32XP environment

[TeaAndBiscuits]

I created a labview DLL  using LabVIEW 2010 32 bit development environment.
Then I loaded it on different computer that does not have LabVIEW, but has LabVIEW runtime engine 2010 only

I treid to load it
on 32bit WinXP, LV Runtime 32 bit 2010...............load was successful
on 64bit WinXP, LV Runtime 32 bit 2010...............load failed
on 64bit Win 7, LV Runtime 32 bit 2010...............load failed
on 64bit Win 7, LV Runtime 64 bit 2010...............load failed

Looking to identify, to run such DLL in above environment, what is required?

Sandeepvd,

Are you calling your DLL from LabVIEW?  If so you will not be able to call a 32-bit DLL in 64-bit LabVIEW.  See the following KB:

Can I Call a 32-bit DLL from 64-bit LabVIEW?
