I currently have this in this part of Inno script
[Run]
Filename: {app}\bin\vcredist_x86.exe; Parameters: "/q:a /c:""VCREDI~3.EXE /q:a /c:""""msiexec /i vcredist.msi /qn"""" """; WorkingDir: {app}\bin; StatusMsg: Installing Visual Studio 2010 C++ CRT Libraries...
It will run vcredist installer during app installation. But the problem with this is that if the user has it already installed it throws things like
- Repair/Remove
- Already newer version detected
Is there any way to avoid this and only run this installer if needed? What should i add to Inno script?
EDIT:
With the help of @John links i made it witht he following function added
I also used this site for refference to get visual studio 2010 crt++ product code and used Uninstall folder in registry to detect if its installed.
function InitializeSetup(): Boolean;
var
ErrorCode: Integer;
RedistInstalled : Boolean;
Result1 : Boolean;
begin
RedistInstalled := RegKeyExists(HKLM,'SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{196BB40D-1578-3D01-B289-BEFC77A11A1E}');
if RedistInstalled then
begin
Result := true;
end else
begin
RedistInstalled := RegKeyExists(HKLM,'SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{196BB40D-1578-3D01-B289-BEFC77A11A1E}');
if RedistInstalled then
begin
Result := true;
end else
begin
Result1 := MsgBox('This setup requires Microsoft Visual C++ 2010 Redistributable Package (x86). Please install Visual C++ 2010 Redistributable Package (x86) and run this setup again. '#13#10' '#13#10'Do you want to download Microsoft Visual C++ 2010 Redistributable Package (x86) now?',
mbConfirmation, MB_YESNO) = idYes;
if Result1 =false then
begin
Result:=false;
end else
begin
Result:=false;
ShellExec('open',
'http://download.microsoft.com/download/5/B/C/5BC5DBB3-652D-4DCE-B14A-475AB85EEF6E/vcredist_x86.exe',
'','',SW_SHOWNORMAL,ewNoWait,ErrorCode);
end;
end;
end;
end;
It would still be nice if however installer would continue after downloading/installing or that i could somehow adapt my previous code that runs included(with setup) installer:
[Run]
Filename: {app}\bin\vcredist_x86.exe; Parameters: "/q:a /c:""VCREDI~3.EXE /q:a /c:""""msiexec /i vcredist.msi /qn"""" """; WorkingDir: {app}\bin; StatusMsg: Installing Visual Studio 2010 C++ CRT Libraries...
but this is still good enough.
