I want to check if there is a certain file before starting to extract, because if there is that file installation must stop. Is it possible?
I just found a way; I've used the CurStepChanged event method and wait there for CurStep=ssInstall which indicates the installation process is about to start. At that time I check if the file exists, and if so, I terminate the setup process:
[Code]
procedure ExitProcess(uExitCode: UINT);
external 'ExitProcess#kernel32.dll stdcall';
procedure CurStepChanged(CurStep: TSetupStep);
begin
if CurStep = ssInstall then
begin
if FileExists(ExpandConstant('{app}\.versionC204v1')) then
begin
MsgBox('A patched version detected. Setup will now exit.', mbInformation, MB_OK);
ExitProcess(0);
end;
end;
end;

When I compile and then run my Inno script, I want to parse hard coded command line switches. So, instead of running my script as c:\myInstall.exe /myswitch I want to run it via IDE and have this switch included at the start here
With this code, I want to retrieve this switch in ParamStr(x)
function MyParams(param: String): string;
begin
MsgBox(ParamStr(3), mbError, MB_OK);
Result := MyParameter;
end;
{Parameter Detection--end}
function InitializeSetup(): Boolean;
begin
MyParams('XXX');
end;
I found a tool, which does this for you - you can set DEBUG variables if you use
Inno Script Studio
I have a setup for installing my application, and I need to run the application after successfully installing. I used postinstall to do this.
but it shows a checkbox and the user can uncheck it. I need to run the application without asking because of it kinda service which needs to runs at startup. if the user unchecked it he needs to restart the PC to launch.
So I can use the Filename: "{app}\myapp.exe" code without any flags in the Run section to launch the application but the problem is, It runs immediately after installing not after the finish button clicked.
The first issue is my application has an instruction window. it shows up at the launch so the setup window goes to the back. And the second issue is my application does not allow terminating unless uninstall becouse it need to run in the background. Setup waiting to process end to finish.
Is there any way to run the application after the finish button click in inno setup?
Simplifying the answer from Run Files and Programs according to custom checkboxes after clicking on Finish Button in Inno Setup, you can use a code like this:
[Code]
function NextButtonClick(CurPageID: Integer): Boolean;
var
ResultCode: Integer;
Path, Msg: string;
begin
if CurPageID = wpFinished then
begin
Path := ExpandConstant('{app}\MyProg.exe');
if ExecAsOriginalUser(Path, '', '', SW_SHOW, ewNoWait, ResultCode) then
begin
Log('Executed MyProg');
end
else
begin
Msg := 'Error executing MyProg - ' + SysErrorMessage(ResultCode);
MsgBox(Msg, mbError, MB_OK);
end;
end;
Result := True;
end;
Replace ExecAsOriginalUser with Exec, if you want to run the program with elevated/Administrator privileges (if the installer uses them at all).
Add code section to your script like this:
[Code]
procedure CurStepChanged(CurStep: TSetupStep);
var
ResultCode: Integer;
begin
if CurStep = ssDone then
Exec(ExpandConstant('{app}\MyProg.exe'), '', '', SW_SHOW, ewNoWait, ResultCode);
end;
It will be triggered only on a success installation.
Use ExecAsOriginalUser instead of Exec if you don't want the exe run as admin.
I am trying to create an Inno Setup installer that will require a password from the user if the application has never been installed on the local machine.
I have the script that gets a password, and I have a Code section that checks for the existence of the uninstall registry key, but being new to Inno Setup scripting, I'm not sure how to link the two parts together.
Can anyone explain how to forgo the user from entering a password if the app is already installed?
Here is the (test) script...
#define myAppID "2B7D6E48-74A8-4070-8BA7-621115D6FD00"
[Setup]
AppId={{{#myAppID}}
Password=123456
[Code]
function checkForPreviousInstall(): Boolean;
begin
Result := False;
if RegKeyExists(HKEY_LOCAL_MACHINE,'SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{#myAppId}_is1') or
RegKeyExists(HKEY_CURRENT_USER, 'SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{#myAppId}_is1') then
begin
MsgBox('The application is installed already.', mbInformation, MB_OK);
Result := True;
end;
end;
Skip the password page, if the application is installed already.
Use ShouldSkipPage event function:
function ShouldSkipPage(PageID: Integer): Boolean;
begin
Result := False;
if (PageID = wpPassword) and checkForPreviousInstall then Result := True;
end;
I know there is already question Execute different command in Inno Setup Run section based on Windows version with very good answer.
My question is how to perform different blocks of commands for different target Windows versions. My problem is that I have ~10-15 commands that need to perform if target version is Windows 7 and the ~same amount of different commands for Windows 8 or above.
Is it possible to avoid the need to add ; OnlyBelowVersion: 6.2 after each command needed for first case and ; MinVersion: 6.2 after each command in the second block?
I know there is preprocessor conditions "#if", #else and #endif but that of course works only at compilation time
The question and answers Determine Windows version in Inno Setup although may look similar to this question are NOT answering it. I know how to determine Windows version in Inno Setup. I also know about those ; MinVersion: 6.2 and ; OnlyBelowVersion: 6.2 options. I am asking if it is possible to specify a block of commands (10-15 commands) and apply that option to entire block, not to each and every command individually.
The goal is not to avoid "cryptic version numbers" but to avoid repeating the same condition many times. And to avoid risk of forgetting it when block will grow over the time.
The solution that I found so far is to use CurStepChanged procedure:
procedure CurStepChanged(CurStep: TSetupStep);
begin
if CurStep = ssPostInstall then
if IsWindows8OrLater() then
MsgBox('Running on Windows 8 Or Later', mbInformation, MB_OK)
{ 15 comands or call of W8-specific procedure goes here }
else begin
MsgBox('Running on Windows 7', mbInformation, MB_OK);
{ 15 comands or call of W7-specific procedure goes here }
end;
end;
But it looks a bit ugly to me...
There are no block-control features in the .iss file.
All you can do, to avoid repeating the cryptic version numbers, is to define a preprocessor variable like:
#define Windows8AndNewer "MinVersion: 6.2"
#define Windows7AndOlder "OnlyBelowVersion: 6.2"
[Run]
Filename: "Windows8-Command1.exe"; {#Windows8AndNewer}
Filename: "Windows8-Command2.exe"; {#Windows8AndNewer}
Filename: "Windows7-Command1.exe"; {#Windows7AndOlder}
Filename: "Windows7-Command2.exe"; {#Windows7AndOlder}
The only other way is to reimplement the [Run] section in the [Code] using the Exec function:
procedure Run(FileName: string);
var
ResultCode: Integer;
begin
Exec(FileName, '', '', SW_SHOW, ewWaitUntilTerminated, ResultCode);
{ some error checking }
end;
procedure CurStepChanged(CurStep: TSetupStep);
begin
if CurStep = ssPostInstall then
begin
if GetWindowsVersion() >= $06020000 then
begin
Log('Running on Windows 8 or later');
Run('Windows8-Command1.exe');
Run('Windows8-Command2.exe');
end
else
begin
Log('Running on Windows 7 or older');
Run('Windows7-Command1.exe');
Run('Windows7-Command2.exe');
end;
end;
end;
I am using Inno Setup to distribute my application.
Is it possible to check in Inno Script for a particular condition and download and install some file from internet if required.
Inno Setup 6.1 and newer has a built-in support for downloads. No 3rd party solution are needed anymore.
Check the Examples\CodeDownloadFiles.iss in Inno Setup installation folder.
The important parts of the example are:
[Files]
; These files will be downloaded
Source: "{tmp}\innosetup-latest.exe"; DestDir: "{app}"; Flags: external
Source: "{tmp}\ISCrypt.dll"; DestDir: "{app}"; Flags: external
[Code]
var
DownloadPage: TDownloadWizardPage;
function OnDownloadProgress(const Url, FileName: String; const Progress, ProgressMax: Int64): Boolean;
begin
if Progress = ProgressMax then
Log(Format('Successfully downloaded file to {tmp}: %s', [FileName]));
Result := True;
end;
procedure InitializeWizard;
begin
DownloadPage := CreateDownloadPage(SetupMessage(msgWizardPreparing), SetupMessage(msgPreparingDesc), #OnDownloadProgress);
end;
function NextButtonClick(CurPageID: Integer): Boolean;
begin
if CurPageID = wpReady then begin
DownloadPage.Clear;
DownloadPage.Add('https://jrsoftware.org/download.php/is.exe', 'innosetup-latest.exe', '');
DownloadPage.Add('https://jrsoftware.org/download.php/iscrypt.dll', 'ISCrypt.dll', '2f6294f9aa09f59a574b5dcd33be54e16b39377984f3d5658cda44950fa0f8fc');
DownloadPage.Show;
try
try
DownloadPage.Download;
Result := True;
except
SuppressibleMsgBox(AddPeriod(GetExceptionMessage), mbCriticalError, MB_OK, IDOK);
Result := False;
end;
finally
DownloadPage.Hide;
end;
end else
Result := True;
end;

Inno Download Plugin by Mitrich Software.
It's an InnoSetup script and DLL, which allows you to download files as part of your installation.
It supports FTP, HTTP and HTTPS.
It's kind of a drop-in replacement for InnoTools Downloader. Only few changes required.
It brings a decent download display and HTTPS and Mirror(s) support.
Example:
#include <idp.iss>
[Files]
Source: "{tmp}\file.zip"; DestDir: "{app}"; Flags: external; ExternalSize: 1048576
[Code]
procedure InitializeWizard();
begin
idpAddFileSize('http://127.0.0.1/file.zip', ExpandConstant('{tmp}\file.zip'), 1048576);
idpDownloadAfter(wpReady);
end.
Yes, there is a library called InnoTools Downloader which has samples that do pretty much this. They can be conditioned on anything you want using normal Inno code.
Found on Inno 3rd Party is one very similar in scope and style to the Inno Download Plugin, DWinsHs.
Included with an easy and intuitive chm file which requires unblocking to view.
