Installation problem

[JonH]

I'm trying to use madExcept on a Windows XP Pro sp3 system running Delphi 7. When I enable madExcept for a project and try to compile it I get :"Fatal Error: Unit madExcept was compiled with a different version of Windows.CreateProcessW"

Did you happen to modify Windows.pas somehow? Which Delphi 7 version do you have installed (Help -> About)? Mine says Build 4.453.

Not that I'm aware of, my windows.pas is 1218610 bytes and has a modified date of 8/28/08
This version shows Delphi Enterprise Lite Edition v7.3.3.0 (Build 8.1)
I think I recall this version had a bunch of tweaks and patches applied, so that may be the cause of the error.
I'll have to dig out my original Delphi 7 disks and do a clean install from them and see if it works then.

There are 2 other things you could do as an alternative:

(1) You could do a full cleanup, just to be safe that there's no old DCUs flying around somewhere which are causing the problem. The cleanup should work like this:

- uninstall madCollection
- search harddisk and registry for mad*.* and delete everything that belongs to madCollection
- start Delphi to make sure it starts ok with no complaints and no traces of madCollection left
- stop Delphi and reinstall madCollection

Does that make the problem go away?

(2) You could simply copy all the needed madCollection pas files into your project folder. Or you could tell Delphi to also compile the madExcept\Sources folder (and madDisAsm\Sources and madBasic\Sources). This is not a really nice solution, though.

I tried the first suggestion and got the same error. I tried the second but since I just have the free version it doesn't have the source for madExcept and so it gave the same "Unit madExcept was compiled with a different version of Windows.CreateProcessW" error.
Here is the declaration of CreateProcessW in my Windows.pas:

Code: Select all

function CreateProcessW(lpApplicationName: PWideChar; lpCommandLine: PWideChar;
  lpProcessAttributes, lpThreadAttributes: PSecurityAttributes;
  bInheritHandles: BOOL; dwCreationFlags: DWORD; lpEnvironment: Pointer;
  lpCurrentDirectory: PWideChar; const lpStartupInfo: TStartupInfoW;
  var lpProcessInformation: TProcessInformation): BOOL; stdcall;


I just compared it to another Delphi 7 Pro install which has

Code: Select all

function CreateProcessW(lpApplicationName: PWideChar; lpCommandLine: PWideChar;
  lpProcessAttributes, lpThreadAttributes: PSecurityAttributes;
  bInheritHandles: BOOL; dwCreationFlags: DWORD; lpEnvironment: Pointer;
  lpCurrentDirectory: PWideChar; const lpStartupInfo: TStartupInfo;
  var lpProcessInformation: TProcessInformation): BOOL; stdcall;


So it looks like in my system lpStartupInfo is of type TStartupInfoW while in the other system its of type TStartupInfo.
I wonder if this was a bugfix, I found sample code on the internet showing that some newer Delphi versions used TStartupInfoW.

Well, I'm not sure, but it seems that the Delphi complaint is correct, although quite annoying in your case. At this point I don't really know how to help you. Since you're the only user who has ever reported this problem it seems that your Delphi 7 installation is somewhat "special". I can only create precompiled DCU files for the standard installation.

I did a plain install of Delphi 7 Pro without patches and it works without the error, so I should be good for now, thanks.
