如何从以管理员身份运行的Inno Setup安装程序中读取登录用户的注册表HKCU [英] How to read registry HKCU for logged In user from Inno Setup installer running as administrator
问题描述
我的设置设置为以最低特权运行
My setup is set to run with lowest privileges
PrivilegesRequired=lowest
但是我正在以 Admin (右键单击->以admin身份运行,在UAC中输入Admin凭据)执行安装程序,并想在其中检查已登录用户的注册表InitializeSetup()
But I'm executing setup as Admin (right click-> run as admin, enter Admin credential in UAC), and want to check Logged In User's registry in InitializeSetup()
function InitializeSetup(): boolean;
begin
if RegQueryStringValue(HKCU,'SOFTWARE\{some path}','Version', {some value}) then
begin
{ do something here }
end
end
但这会检查管理员帐户的注册表值,不检查已登录用户帐户的注册表值
But this checks the registry value for the Admin Account, not for Logged In User Account
此时是否可以检查已登录的用户注册表?
Is there a way to check the logged in users registry at this point?
推荐答案
首先,您不应尝试从以管理员权限运行的安装程序访问用户环境.那是错误的.
First, you should not try to access a user environment from an installer running with Administrator privileges. That's just wrong.
有关此主题的一般讨论,请参见:
从以管理员身份运行的Inno Setup安装程序中为当前登录的用户安装应用程序.
For a general discussion on this topic, see:
Installing application for currently logged in user from Inno Setup installer running as Administrator.
无论如何,您可以使用下面的功能.
Anyway, you can use a function below.
代码结合了以下解决方案:
The code combines these solutions:
- Inno Setup Creating registry key for logged in user (not admin user)
- Inno Setup always installs into admin's AppData directory
function ReqQueryValueOfOriginalUser(var ResultStr: String): Boolean;
var
Uniq: string;
TempFileName: string;
Cmd: string;
Key: string;
Value: string;
Params: string;
Lines: TArrayOfString;
Buf: string;
ResultCode: Integer;
P: Integer;
begin
Log('Querying registry value of original user');
Uniq := ExtractFileName(ExpandConstant('{tmp}'));
TempFileName :=
ExpandConstant(Format('{commondocs}\appdata-%s.txt', [Uniq]));
Cmd := ExpandConstant('{cmd}');
Key := 'HKEY_CURRENT_USER\Software\{some path}';
Value := 'Version';
Params := Format('/C reg.exe QUERY "%s" /v "%s" > "%s"', [Key, Value, TempFileName]);
Result := False;
if ExecAsOriginalUser(Cmd, Params, '', SW_HIDE, ewWaitUntilTerminated, ResultCode)
and (ResultCode = 0) then
begin
if LoadStringsFromFile(TempFileName, Lines) then
begin
if (Length(Lines[0]) > 0) or
(Lines[1] <> Key) then
begin
Log(Format('Unexpected output of reg.exe QUERY: "%s" - "%s"', [
Lines[0], Lines[1]]));
end
else
begin
Buf := Trim(Lines[2]);
if Copy(Buf, 1, Length(Value)) <> Value then
begin
Log(Format('Unexpected output of value query: "%s"', [Buf]));
end
else
begin
Buf := Trim(Copy(Buf, Length(Value) + 1, Length(Buf) - Length(Value)));
P := Pos(' ', Buf);
if P = 0 then
begin
Log(Format('Cannot find type and value separator in "%s"', [Buf]));
end
else
begin
ResultStr := Trim(Copy(Buf, P + 1, Length(Buf) - P));
Log(Format('Value is "%s"', [ResultStr]));
Result := True;
end;
end;
end;
end
else
begin
Log(Format('Error reading %s', [TempFileName]));
end;
DeleteFile(TempFileName);
end
else
begin
Log('Error querying registry key of original user');
end;
Result := True;
end;
