If you’re trying the keys listed in my post, you might try looking around in the comments. People have said that I did not fully write out the keys. I simply copy and pasted from another source, so I can’t say I know very much about this problem.

Also, if you’re running Windows 7 x64, you might have to try a different DLL, as I recall there may be x32 and x64 versions of the vbscript.dll.

This sounds like the solution I’m looking for but I can’t get it to work. (I’m practically computer illiterate). When I input the first command to unregister the vbscript, I get the following response

ERROR: Invalid Key Name.
TYPE “Reg DELETE /?” for usage.

I have no idea what that means or what I should do next. Please I’m desperate. I can’t install my Verizon air card and Verizon says it’s a Windows 7 glich. MicroSoft says I must pay $49.99/hr for support (I just bought this machine 2 weeks ago and I should pay for support??). I can’t load my Palm Pilot software – same 2738 error.

Please can I get some help???

Guys. Both commands given above are correct. Right after pasting it into the command prompt window retype both ” chars. Worked for me.

Thanks, how others sad, I had to delete he keys throught “regedit”, but the new registration works fine and I could install the Cisco VPN 5.04 on Windows 7 32-bits. Don’t forget that you have to register jscript.dll too.

Thanks. This solved the problem not only for uninstalling Cisco VPN from Windows 7, but also Blackberry Desktop software.

I couldn’t get your “reg delete” commands to work, but I was able to run “regedit” and use that to delete the keys you listed. Followed the remaining instructions after that and everything uninstalled perfectly.

For people with Windows 7 who have tried the instructions on other sites to solve “Internal Error 2738″ without any luck, this post has the critical missing piece.

You are a genius, Thank you for your help. I know all what you were talking about but it did not occurred to me to unregister it first. You are the man. I am Win7 user happy to have installed Cisco VPN Client thanx to you.

In Vista 64-bit, the relevant keys to delete first are in:

HKEY_CURRENT_USER\Software\Classes\Wow6432Node\CLSID\{F414C262-6AC0-11CF-B6D1-00AA00BBBB58}

HKEY_CURRENT_USER\Software\Classes\Wow6432Node \CLSID\{B54F3741-5B07-11CF-A4B0-00AA004A55E8}

(note the Wow6432Node)

Thank you! Manually deleting and reregistering works on my system too.
