我安装了dotnet framework 3.5作为先决条件,下面是我的代码。 当我运行此代码时,出现以下错误。有人可以让我知道为什么“tmp”文件夹不能识别文件。 编辑 我已经使用“AfterInstall”而不是“BeforeInstall”,如本示例代码中所述,它工作正常。安装框架作为inno安装程序的先决条件时,在tmp文件夹中找不到文件错误
当我评价我找到的路径如下常数。
[Files]
Source: "dotnetfx35setup.exe"; DestDir: {tmp}; Flags: deleteafterinstall; BeforeInstall: Install35Framework; Check: Framework35IsNotInstalled
[Code]
function Framework35IsNotInstalled: Boolean;
begin
if IsDotNetDetected('v3.5' , 1) then
begin
Result := False;
end else begin
Result := True;
end;
end;
procedure Install35Framework;
var
StatusText: string;
ResultCode: Integer;
begin
StatusText := WizardForm.StatusLabel.Caption;
WizardForm.StatusLabel.Caption := 'Installing .NET framework 3.5...';
WizardForm.ProgressGauge.Style := npbstMarquee;
try
if not Exec(ExpandConstant('{tmp}\dotnetfx35setup.exe'), '/q /norestart', '', SW_SHOW, ewWaitUntilTerminated, ResultCode) then
begin
{ you can interact with the user that the installation failed }
MsgBox('.NET framework 3.5 installation failed with code: ' + SysErrorMessage(ResultCode) + '.',mbError, MB_OK);
end;
finally
WizardForm.StatusLabel.Caption := StatusText;
WizardForm.ProgressGauge.Style := npbstNormal;
end;
end;
我的回答对你有帮助吗? –
