PsExec not working on 64bit computers

  • 772

When copying the .exe to a 64bit Windows computer using the -c flag with PsExec, there's an error executing it, PsExec just stalls there.

Anyone else experiencing this?

  1. Is this thread on social.msdn relevant?

    The poster was getting problems with PsExec on some 64 bit machines, but was getting a "... device not functioning..." message. However, in his own reply he states:

    After some more testing I noticed the problem only occurred on WES 7 64 Bit.
    Any retail version 32 or 64 bit and WES 7 32 bit would work fine.
    Then I remembered the following update:
    KB982199 is an update for 64-bit systems which fixes the following issue: CreateProcess fails for 32 bit Applications on Windows Embedded Standard 7 64-bit runtimes when redirection disabled
    After installing this update the problem was solved.

  2. const string subkey = "Software\Sysinternals\PsExec";

            if (Environment.Is64BitOperatingSystem)
        {
            // For 64 Bit PC
            RegistryKey registryKey64 = RegistryKey.OpenBaseKey(RegistryHive.CurrentUser, RegistryView.Registry64);
            RegistryKey NDPKey64 = registryKey64.OpenSubKey(subkey);
            if (NDPKey64 != null)
            {
                Registry.CurrentUser.OpenSubKey(subkey, true).SetValue("EulaAccepted", 1, RegistryValueKind.DWord);
            }
            else
            {
                RegistryKey regKey64 = registryKey64.OpenSubKey("Software", true);
                regKey64.CreateSubKey("Sysinternals\\PsExec", RegistryKeyPermissionCheck.ReadWriteSubTree);
                Registry.CurrentUser.OpenSubKey(subkey, true).SetValue("EulaAccepted", 1, RegistryValueKind.DWord);
            }
        }
        else
        {
            //For 32 bit PC
            RegistryKey registryKey32 = Registry.CurrentUser.OpenSubKey(subkey);
            if (registryKey32 != null)
            {
                Registry.CurrentUser.OpenSubKey(subkey, true).SetValue("EulaAccepted", 1, RegistryValueKind.DWord);
            }
            else
            {
                RegistryKey regKey32 = Registry.CurrentUser.OpenSubKey("Software", true);
                regKey32.CreateSubKey("Sysinternals\\PsExec", RegistryKeyPermissionCheck.ReadWriteSubTree);
                Registry.CurrentUser.OpenSubKey(subkey, true).SetValue("EulaAccepted", 1, RegistryValueKind.DWord);
            }
        }
