InnoSetup starting a PB program before updating

[Mike Doty]

Install a pre-installation program with InnoSetup and shell to it before installing other files.
This allows different checks or performing new actions if required with any version.
A splash screen is optional pbwin10\samples\sdk\hellowin

This should have an option to terminate the install.
Change (Code) to bracket Code bracket

[Files]
Source: splash.exe; DestDir: {app}; Flags: ignoreversion overwritereadonly; AfterInstall:PowerBasicPreInstall


(Code)
procedure PowerBasicPreInstall();
var
ErrorCode: INTEGER;
begin
  //ShellExec('', ExpandConstant('{app}\splash.exe'),'', '', SW_SHOW, ewNoWait, ErrorCode);
  ShellExec('', ExpandConstant('{app}\splash.exe'),'', '', SW_SHOW, ewWaitUntilTerminated, ErrorCode);
  //MsgBox('This is not needed', mbInformation, MB_OK);
end;

I don't run a program at start; I call a function in a PB-Created DLL.

This code ensures the correct minimum version of the software is installed and that no instances are running; and it re-serializes the new EXE with the user's existing serial number.

Since I'm not a Pascal programmer I do all the really neat stuff in a function in a PB-Created DLL.

var
   ResultCode: Integer;
//        "During Setup, a special 'files:' prefix to instruct Setup to automatically extract the DLL from the
//       [Files] section may also be used.
function TsiUpgradeCheck (szTmp, szParam, szSpare: String): Integer;
external '[email protected]:tsiupgrade.dll';


function InitializeSetup(): Boolean;
var
	sFile: String;
	sFullFile: String;
	sMsg : String;
	sTmp    : String;
	sSpare  : String;
	bMsgBox : Boolean;
	iZero   : Integer;
	iOne    : Integer;
	iTwo    : Integer;
	iThree  : Integer;
	iFour   : Integer;
	iFive   : Integer;
	bMutex  : Boolean;
	
begin
 //
 bMutex     := CheckForMutexes ('provider_payment_partner_v_300');

 if bMutex = True then
 begin
       sMsg    := 'Cannot run upgrade - PPPS is currently executing.';
       msgbox (sMsg,mbCriticalError, MB_OK);
       Result  := False;
       bMsgbox := False;

 end;
 if bMutex = False then
 begin
    iZero      := 0;
    iOne       := 1;
    iTwo       := 2;
    iTHree     := 3;
    iFour      := 4;
    iFive      := 5;
    sFile      := 'ppps.exe';           // file to be extracted to {tmp}: the DLL will need it
    sFullFile  :=  ExpandConstant('{tmp}\'+ sFile)
    sTmp       :=  ExpandConstant('{tmp}')
    sSpare     := 'log=pppsupgrade.log'

    // get the new PPPS.EXE into {tmp}
    ExtractTemporaryFile (sFile)
    // CALL the UpgradeCheck function. Returns zero if OK to continue.
    // this function with this parameter is looking for 3.0 to be installed.
    // which is exactly what we want.
    // I think for 3.2 I want to also check for 3.2 installed.
    // TsiUpgradeCheck does what...?
    //
    ResultCode :=  TsiUpgradeCheck (sTmp,'PPPS300',sSpare);   // key for PPPS 3x3x upgrade
    // old exec code was here
    // I could check here if not zero, then retry with PPPS 310?
    if ResultCode > 0 then
    begin
        ResultCode :=  TsiUpgradeCheck (sTmp, 'PPPS310', sSpare)
    end;
    // I think just adding this code will work for upgrade
    if ResultCode > 0 then
    begin
        ResultCode := TsiUpgradeCheck (sTmp, 'PPPS320', sSpare)
    end;
    // at this point if ResultCode = 0 then at least one of 3.0, 3.1 or 3.2 is installed and we may proceed.
    case ResultCode of
              iZero:
                 Result  := True

Thanks much, MM!

How would I run or shell to a PB program before InnoSetup starts updating?

I want to backup a folder, test the backup and assure nobody is using anything before updating.

[Run] with a flag within InnoSetup?
