I cannot login I don't have a My Cloudmark account

When I install Cloudmark DesktopOne, I see "Error 2738".

Issue:

When installing Cloudmark DesktopOne on Windows Vista or Windows 7, you may see "Error 2738". If this happens, follow the instructions below.

Solution:

For 32-bit Windows users:

  1. Perform a system-wide search for "vbscript.dll" on your computer.

    Once you find it, make a note of the location, because you'll need it later. Usually, it's located in C:\Windows\System32, but this can change based on your version of Windows.

  2. Click the Windows icon (what used to be the Start button in Windows XP/2000/NT), select All Programs > Accessories.
  3. Right click on "Command Prompt" to open the pop-up menu.
  4. Select "Run As Administrator".
  5. Click "Continue".
  6. In the Command Prompt window, type "cd (path)".

    So, for example,if the vbscript.dll file is located in the system32 folder as expected, you would type "cd c:\windows\system32".

  7. On the next line, type "regsvr32 vbscript.dll".
  8. Press the Enter key.

    You should receive a confirmation that it was loaded without problems.

  9. Proceed with the Cloudmark installation.

For 64-bit Windows users:

  1. Perform a system-wide search for "vbscript.dll" and "jscript.dll" on your computer.
  2. Once you find it, make a note of the location, because you'll need it later. Usually, it's located in C:\Windows\Syswow64, but this can sometimes change based on your version of Windows.
  3. Open an elevated Command Prompt by clicking on the Start globe or button, choosing "All Programs", then "Accessories". Right-click on "Command Prompt" and choose "Run As Administrator."
  4. At the blinking cursor type in: cd C:\Windows\SysWOW64 and then press the Enter button on your keyboard (If your syswow64 folder is located somewhere else, type in the actual path.)
  5. At the blinking cursor type in: regsvr32 vbscript.dll (then press enter.) You should receive a message that the .dll was successfully registered.
  6. At the blinking cursor type in: regsvr32 jscript.dll (then press enter.) You should receive a message that the .dll was successfully registered.

At this point, you should be able to close the Command Prompt window and install Cloudmark DesktopOne.

If this does not resolve your issue, please do the following:

For 32-bit Windows users:

  1. Close Outlook.
  2. Click on the Start menu, choose Run, type cmd and click OK.
  3. Run this command: reg delete "HKCU\SOFTWARE\Classes\CLSID\{B54F3741-5B07-11CF-A4B0-00AA004A55E8}" /f

For 64-bit Windows users:

  1. Close Outlook.
  2. Click on the Start menu, choose Run, type cmd and click OK.
