Internal Error 2738 with VPN Client on Windows 7

My father was pre-ordering the Windows 7 Home Premium Upgrade today. He needed to know if he should get a copy for my mother’s computer which currently runs Windows XP. She uses it for work primarily and because of that, uses the Cisco VPN client. I have a number of computers running the Windows 7 RC so I decided it would be a good idea to test out the client before I told him if he should get one for her computer.

I extracted the setup and then tried to run the installer and that’s where the problems started.

An error came up when the installer progress bar was half way:

Internal Error 2738

A lot of good that does, right? Well, a quick google search and a link later, we get a solution:

1. Run a command prompt in administrator mode (Start/All Programs/Accessories/ right click on Command Prompt, select Run As Administrator)
2. type: cd %systemroot%\system32
3. type: regsvr32 vbscript.dll

That website said this fix was for installing on Windows Vista. I ran through those instructions (I did this when installing some Adobe software for a friend) but it didn’t help. When I ran the installer again, it still threw the same error. I repeated everything multiple times, restarted even but still, no dice.

The second solution (and this too) that I found was the bullseye. The idea is that if you need to register the vbscript.dll, you need to unregister it first. It doesn’t seem as easy as the registering method, but it really isn’t hard if you copy and paste.

If you have these scripting engines registered under HKEY_CURRENT_USER, you need to make sure that you remove that registration and re-register them under HKEY_LOCAL_MACHINE.  You can use the following steps to unregister them from HKEY_CURRENT_USER:

1. Click on the Start menu, choose Run, type cmd and click OK
2. To unregister the VBScript engine, run this command: reg delete “HKEY_CURRENT_USER\SOFTWARE\Classes\CLSID\{B54F3741-5B07-11CF-A4B0-00AA004A55E8}” /f
3. To unregister the JScript engine, run this command: reg delete “HKEY_CURRENT_USER\SOFTWARE\Classes\CLSID\{F414C260-6AC0-11CF-B6D1-00AA00BBBB58}” /f

When you run the code above through the command prompt as an admininstrator, it should say it was successful. For #3 though, I didn’t need it as I wasn’t using JScript, so keep in mind that if you haven’t registered it already, it won’t be successful. (I set the command in bold; copy and paste that.)

Once you do all of that, go back and run the regsvr32 method again. That should do it.

We’re getting a couple pre-ordered copies of Windows 7 and my mother is going to make the big switch between XP and 7. Good luck with Windows and Cisco VPN!
