[nuoya pan]

The check function reture true,I can get messagebox with "do not need install webview2",but the webview installer always run.When I add "Parameters: /q" after check funciton WebViewRunTimeinstalled, webview installer will be broken with error.Here is sniper code.

[Run]
Filename: "{app}\{#VCFile}";Check:VCinstalled;WorkingDir: {tmp}; Flags: skipifsilent
Filename: "{app}\{#WebViewFile}"; Check:WebViewRunTimeinstalled; WorkingDir: {tmp}; Flags: skipifsilent
Filename: "{app}\{#PrinterDriver}"; Parameters: /q; WorkingDir: {tmp}; Flags: skipifsilent
Filename: "{app}\{#MyAppExeName}"; Description: "{cm:LaunchProgram,{#StringChange(MyAppExeName, '&', '&&')}}"; Flags: nowait postinstall skipifsilent

       
[Code]
function WebViewRunTimeinstalled(): Boolean;
    var
     key1: String;
     key2: String;
     version1: String;
     version2: String;
    begin
    Result := false;
    if IsWin64 then begin
        key1 := 'SOFTWARE\WOW6432Node\Microsoft\EdgeUpdate\Clients\{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}';
        key2 := 'Software\Microsoft\EdgeUpdate\Clients\{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}';

        if RegQueryStringValue(HKLM64, key1, 'pv', version1) then
            Result := trim(version1) <>'';
            MsgBox('version:'+version1,mbInformation,MB_OK);
        end;

        if not Result then  begin
            if RegQueryStringValue(HKCU64, key2, 'pv', version2) then  begin
                    Result := trim(version2) <> '';
                    end
            else  begin
              MsgBox('read key2  failure',mbInformation,MB_OK);
        end;
    end;

    if result then
      MsgBox('do not need install webview2', mbConfirmation, MB_OK);
  end;

if the result of the check function is true, then the entry is ran. If you don't want it to run, return false!
