here is a possible solution, inside InitializeWizard() method you check on the registry for the specific version of the .net framework that you need, if it is not present, then you can include, as a part of your inno installer, the framework web installer, and you can execute it, and wait for it to conclude, and depending on whether it was successfully installed or not, you may choose to continue or to abort the install.

Also, have in mind that some .net framework installers may require a reboot after installation, in that case, you also may want to include a key on the registry, under the run-once or run keys, so your installer gets called after the reboot (in case the user has chosen to reboot immediately after install).

Here is an example of this:

<pre><code>function CheckIfFrameworkNeeded(): Boolean;
var
 VersionFrameWork: Cardinal;
 FrameWorkNeeded: Boolean;
begin
 FrameWorkNeeded := true;
 //**********************************************************************
 // Check Fot Framewok 3.5.
 //**********************************************************************
 if (RegQueryDWordValue(HKLM, 'Software\Microsoft\NET Framework Setup\NDP\v3.5', 'Install', VersionFrameWork)) then
 begin
 if (VersionFrameWork = 1) then
 FrameWorkNeeded := false
 end;

 Result := FrameWorkNeeded;
end;

function Install_NETFramework() : Integer;
var
 hWnd: Integer;
 ResultCode: Integer;
 dotnetRedistPath: string;
 outVar : string;
begin

 dotnetRedistPath:= ExpandConstant('{tmp}\dotnetfx35setup.exe');

 //*********************************************************************************
 // Run the install file for .NET Framework 3.5. This is usually dotnetfx35setup.exe from MS
 //***********************************************************************************

 if Exec(ExpandConstant(dotnetRedistPath), '', '', SW_SHOW, ewWaitUntilTerminated, ResultCode) then
 begin
 // ResultCode contains the exit code
 case ResultCode of
 // 1641 The requested operation completed successfully. The system will be restarted so the changes can take effect.
 // 3010 The requested operation is successful. Changes will not be effective until the system is rebooted.
 1641:
 begin
 Result := 1;
 end
 3010, 0:
 begin
 Result := 0;
 end else // -> case default
 begin
 Result := -1;
 end
 end;
 end else
 begin
 //handle failure if necessary; ResultCode contains the error code
 Result := -1;
 end;
end;

procedure InitializeWizard();
var
 frameworkNeeded: Boolean;
 installerPath: String;
 res: integer;
begin
 frameworkNeeded := CheckIfFrameworkNeeded();
 if (frameworkNeeded = true)then
 begin
 if MsgBox('This setup requires the .NET Framework 3.5.'#13 + 'The .NET Framework can be obtained from the web.'#13 + 'Would you like to do this now?', mbConfirmation, MB_YESNO) = IDYES then
 begin
 // register in the registry the path to your current installer, so it gets called after a reboot
 RegWriteStringValue(HKEY_LOCAL_MACHINE, 'SOFTWARE\Microsoft\Windows\CurrentVersion\Run', 'MyAppKey', installerPath); // installerPath is the path of your installer
 res := Install_NETFramework();
 case res of
 1: // a restart is going to be executed right away so we abort to avoid the reboot from happening
 begin
 Abort;
 end
 0: // a restart is going to be executed later
 begin
 //Delete the key we added before since we don't need it cause we are installing now
 RegDeleteValue(HKEY_LOCAL_MACHINE, 'SOFTWARE\Microsoft\Windows\CurrentVersion\Run', 'MyAppKey');
 // continue with your installation here
 end
 -1: // an error happened
 begin
 Abort;
 end
 end;
 end else
 begin
 //The user has chosen not to install the framework
 MsgBox('The application can not be installed unless the framework 3.5 be installed first.', mbError, MB_OK);
 Abort;
 end;
 end else
 begin
 // the framework is present so continue with your installation here
 end;
end;
</code></pre>

I think you would still need to find a way to get the path of the executing installer, if you want to set the key on the registry, but aside of that, I think this code can help you with your question.
