Recently we just finally ported the application from Delphi 3 to 7. It is a database application and uses Advantage database components. On a few customers using Windows XP Pro with SP1 the application crashes upon startup. In essence we receive the windows error about sending a report to Microsoft. I cannot reproduce this on other PCs with XP Pro SP1. I cannot reproduce this is in the test enviroment. The version in Delphi 3 still runs fine on the machine in question and they are essentially the same program. I have tried removing the XP Manifest and the same problem occurs. We have Delphi 7.0 Build 8.1 Professional. So I'm guessing that somewhere I am importing a library (i.e. in a 3rd party component) that is not available on this particular PC, hence causing the crash. I am further guessing this because some of the 3rd party components have changed and so required updating before being installed in Delphi 7. This is the only explanation I can think of, but wondering if there are any other suggestions out there, or things to look for in particular. One of the largest new 3rd party components is the JEDI library. Thanks Peter Back to top Michael Valverde Guest Posted: Thu Mar 03, 2005 5:27 am    Post subject: Re: Delphi exe crashes on startup Peter, I once ran across something similar. The user had the PC set to 256 colors and it was hosing my Delphi applications. If the other XP machines are the same, then it could be something like this. Good luck!

I noticed this before in Delphi 3 and using the BDE that if using 256 colours or less the program would crash. Unfortunately this is not the case here. Using remote debugger this comes back as "Too Many Concurrent Exceptions". Again, this seems to occur only on this one site, other clients running XP do not have this problem, so I am at a pit of a loss. The bug appears in the System.pas unit, but I am not sure what is triggering it. Again any ideas would be welcome.

Wrong Package versions and building with packages enabled...? With Hyperthreading, probably a likely candidate, the creation order of components could be in the wrong order. This will cause weird, unexplainable crashes at certain times, like startup or close down, that are almost impossible to recreate on a mono (cored) processor machine. Hope that helps...
