Hi, Pascal experts!
I am using Inno SetUp last version to run the installation of my program..
1. I would like to execute my SysInfo.exe(VC++) in order to check envirement on user's machine
before the installation process starts
2. SysInfo.exe must be already inside single setup.exe
3. I need this code in pascal for MyProgram.iss for the Inno Setup script Wizard
So, When user or autorun invokes Setup.exe it, first , executes SysInfo.exe, which is embedded in Setup.exe
than SysInfo.exe checks if the following in tact with the requirements:
OS version
IE version
Screen resolution
Memory needed for installation
DLLs needed to run program and install ones on user's machine
Returns TRUE and installation continues
Returns FALSE and installation process terminates with appropriate message
I , also, wonder if all tasks(envirement checking) above can be done in pascal inside MyProgram.iss for the Inno Setup script Wizard, so, i do not have to use that SysInfo.exe
Thank you in advance

I think, you choosed wrong topic area. As, .ISS files are from InstallShield (a part of the Delphi package).
It could be possible to store additional EXE file inside of a Pascal created EXE file. But, the additional EXE file would have to be extracted in order to run it. Other solutions would require some assembler code to make it work. And, the Pascal linker will not be able to make such an EXE stored inside of annother EXE trick, I believe.
Bellow is the example from Inno SetUp
and all its references of coding are pointing to Pascal
; -- Example1.iss --
; Demonstrates copying 3 files and creating an icon.
; SEE THE DOCUMENTATION FOR DETAILS ON CREATING .ISS SCRIPT FILES!
[Setup]
AppName=My Program
AppVerName=My Program version 1.5
DefaultDirName={pf}\My Program
DefaultGroupName=My Program
UninstallDisplayIcon={app}
Compression=lzma
SolidCompression=yes
OutputDir=userdocs:Inno Setup Examples Output
[Files]
Source: "MyProg.exe"; DestDir: "{app}"
Source: "MyProg.chm"; DestDir: "{app}"
Source: "Readme.txt"; DestDir: "{app}"; Flags: isreadme
[Icons]
Name: "{group}\My Program"; Filename: "{app}\MyProg.exe"
am i in a wrong area?
No. Example1.iss is a script file used by InstallShield or similiar software.
InstallShield is a part of Delphi software package. Pascal does not have any such a installation system included, as far as I know. (Borland Pascal for sure) But, it is possible, InstallShield is a part of other software development systems.
For-Soft!
The following code works fine and was taking
from the Pascal scripting section of Inno Setup documentation.
except you suggested to use Exec(..)
Now, as a part of original question, i need to return TRUE or
FALSE inside DoPreInstall() scope from my SysInfo.exe(written in VC++)
I can write some values to regestry right from SysInfo.exe
(unless you show me a better way to do it)
than I need your help on how to read those values from regestry
and cancel or proceed with installation depends on the results from registry.
thanks again

[Code]
procedure DoPreInstall();
var
ResultCode: Integer;
begin
Exec(ExpandConstant('{app}
ewWaitUntilTerminated, ResultCode);
end;
procedure DoPostInstall();
begin
MsgBox('Just about to finish installation of MyProg.exe as !', mbInformation, MB_OK);
end;
procedure CurStepChanged(CurStep: TSetupStep);
begin
if CurStep = ssInstall then begin
DoPreInstall();
end else if CurStep = ssPostInstall then begin
DoPostInstall();
end;
end;

I think you should consider unsing an application exit code to pass some information from the SysInfo.exe. This code will be available in the ResultCode, probably.
Yet. The EXEC procedure syntax used in your code is not comming from Borland Pascal library. And Inno Setup is made with Delphi applicacion builder, as far as I know.
Delphi is sort of a newer Pascal version. The language rules are very similiar. I still believe you will find a better help in the Delphi topic area.

uses Dos;
var
ProgramName, CmdLine: string;
begin
ProgramName:='SomeProg.exe
CmdLine:=''; (* Options for the program goes here *)
SwapVectors;
Exec(ProgramName, CmdLine);
SwapVectors;
End.
>>wonder if all tasks(envirement checking)...
Don't think so... maybe what kind of data you want to extract from PC??? what OS...
BTW... are you sure you don't want DELPHI help instead of PASCAL???
