The DynDNS Updater cannot continue without the proper certificates.

Please see the answer to this question, since it sounds like it may be the same problem.

I managed to solve this problem by using installation monitoring tools. I used Spyme to find which files changed and Regsnap to compare the registry changes. After removing the Windows Explorer related changes (like last opened files etc) I had the DynDNS Updater specific changes. So to manually install DynDNS Updater do the following:

1. Install it on a regular Windows XP PC
2. Copy these folders over: 2.1. C:\Documents and Settings\All Users\Application Data\DynDNS 2.2. C:\Documents and Settings\All Users\Start Menu\Programs\DynDNS Updater 2.3. C:\Documents and Settings\All Users\Start Menu\Programs\Startup 2.4. C:\Program Files\DynDNS Updater
3. Create a text file named "DynDNS Updater.reg" and paste the following code at the end of this message into it.
4. Double click the .reg file and allow it to be imported
5. Restart Windows
