尝试在％AppData％中执行.exe时访问被拒绝 [英] Access denied when trying to execute a .exe in %AppData%

问题描述

我正在尝试使用我的在此处找到的RemoveDrive.exe Java应用程序.我将其保存在JAR中，并使用以下代码将其提取到一个临时文件中，但是当我尝试运行它时，我得到一个IOException，其内容为CreateProcess error=5, Access is denied.该程序通常不需要管理员权限.关于可能导致此问题的原因有什么想法吗?

I'm trying to use RemoveDrive.exe, found here, in my Java application. I have it in my JAR, and I'm extracting it to a temporary file using the following code, however when I try to run it I get an IOException which says CreateProcess error=5, Access is denied. The program doesn't normally need admin priviledges though. Any ideas on what could be causing the issue?

            File RDexe = File.createTempFile("rmvd", ".exe");

            InputStream exesrc = (InputStream) GraphicUI.class.getResource("RemoveDrive.exe").openStream();
            FileOutputStream out = new FileOutputStream(RDexe);

            byte[] temp = new byte[1024];
            int rc;

            while((rc = exesrc.read(temp)) > 0)
                out.write(temp, 0, rc);

            exesrc.close();
            out.close();

            RDexe.deleteOnExit();

            // run executable
            Runtime runtime = Runtime.getRuntime();
            System.out.println(RDexe.getPath() + " " + "F:\\" + " -b -s");
            Process proc = runtime.exec(RDexe.getPath() + " " + "F:\\" + " -b");
            InputStream is = proc.getInputStream();
            BufferedReader reader = new BufferedReader(new InputStreamReader(is));

            String line; boolean ejected = false;
            while((line = reader.readLine()) != null)
                if(line.equalsIgnoreCase("failed")) ejected = false;
                else if(line.equalsIgnoreCase("success")) ejected = true;

            reader.close();
            is.close();

更新:如果我启用了内置的Administrator帐户(net user administrator /active:yes)，那么从那里开始一切正常.但是，如果我右键单击并以管理员身份在我的标准帐户中运行，我仍然会收到错误消息，并且UAC甚至都不会征求许可.

UPDATE: If I enable the built-in Administrator account (net user administrator /active:yes), everything works fine from there. However if I right click and run as administrator in my standard account, I still get the error and UAC doesn't even ask for permission.

推荐答案

似乎只在这里涉及到这个问题，我会说这个问题与Windows中的权限有关，与Java无关.

Seeing as though it has only been touched on here, I will say that the issue was related to permissions in Windows, and is not anything to do with Java.

正如我在原始问题中链接到的超级用户"问题中所述，我发现我的普通帐户由于某些未知原因不具有该文件夹的所有权-因此无法执行任何操作；这不仅仅是我用Java创建的临时文件.

As stated in the SuperUser question I've linked to in my original question, I found that my usual account did not have ownership of that folder for some unknown reason - so nothing could be executed; it wasn't just the temporary file I had created in Java.

即使我是管理员，也要获得该文件夹的所有权，我必须启用内置管理员帐户并授予自己所有权.自从我这样做以来，一切都按预期进行.

Even though I am an administrator, in order to take ownership of the folder I had to enable the Built-In administrator account and grant myself ownership. Since I did that, it has all worked as expected.
