Problem running delphi app on AMD64 chips
Posted on 2005-04-15
Hi, we have an app written in Delphi 5 that will not run (wont even start up) on some AMD64 chip machines running XP.
We have never had a problem with any other machine (Intel / AMD, or Operating system).
Some AMD machines that have displayed this problem have been fixed by applying a bios update, but other machines still have problems even after the bios update has been run.
I searched on Google and there are some issues with Windows XP Service Pack 2 and some new security feature re stack allocation etc, but found nothing pointing to any particular calls etc...I suspect this may be the cause, but I am not sure what calls need to be checked / changed to suit XP Sp2.
I am probably asking this question prematurely, as we are currently sourcing an AMD64 machine to try and work out why, but I was wondering if anybody else had experienced this?
