Cisco VPN on Windows 7 64bit

I just got to project, which is hosted on server, where the developers has to connect via Cisco VPN to upload stuff or access SSH. Problem is, that Cisco is unable to create client, which would run with no troubles on Windows 7 64bit!!! Solution is quiet simple:

When You download and start installation of the client (mine was: vpnclient-winx64-msi-5.0.07.0290-k9.exe), You can start installation, but in one of the first steps will error occur:

installation ended prematurely because of an error

Fix which worked for me was following:

  1. Delete whole registry key (better do backup first, by right-click this key and select Export): HKEY_CURRENT_USER\SOFTWARE\Classes\Wow6432Node\CLSID\{B54F3741-5B07-11CF-A4B0-00AA004A55E8}
  2. Start commnad line as an administrator and type: regsvr32 c:\windows\syswow64\vbscript.dll
  3. Start installation again and it should work
  4. Restart your machine after install when promted

  1. HI
    I have been trying to do this fix – for I have the same problem.
    I cannot delete the register entry because it does not exist on the under the
    current user registry.

    Since it was not under the current user registry – I tried registering it and the regsvr32 said it was registered BUT the install still does not work and I still cannot find it in the current user registry. I did find it however in the local machine registry.

    So I am unsure what to do. Any Suggestions?

  2. Thanks a lot for putting this up. Took me a bit to find this solution but glad it was here.

  3. Hi!
    I’m trying to install vpn client version 5.0.07.0290
    Do you have a suggestion for solving the problem if this part of the registry key ({B54F3741-5B07-11CF-A4B0-00AA004A55E8}) does not exist?
    I’ve tried everything else I’m afraid…
    Thanks!

  4. I don’t have that registry key also. The only register key I have started with “B” is only {b2b568c8-3712-4a75-b806-4b3c2fdb06d5}. My O/S is Windows 7 Home Premium 64-bit Service Pack 1. Any suggestion?

  5. Sorry, I do not … I just posted guide, which worked for me and also couple of other ppl here in comments. Maybe just check, if You have correct version of VPN client downloaded.

  6. Delete VPN or old is tricky. If you cannot delete it from connection tab in Network and sharing center, here is the easy way to remove that VPN (after you have tried to remove from Control panel, program and feature not successfully)
    Just follow this steps:
    TO REMOVE VPN
    Network and Sharing Center–>Change adapter settings–>right click on the connection name–>property–>on the ”Do you want to allow”…answer Yes–>click on Configureclick on Driver–>click on Uninstall (100% working, I have tried several times)

    Now you can reinstall the new VPN
