Can't install eCabinet Systems 6

[Garth Kay-Hards]

Hello
I have a new registration and am trying to install the software on Windows XP Home but after entering my registration code I get the following error. I have re-installed the software and retrieved a new download to try but all with the same error.

Revocation information for the security certificate for this site is not available.

Is this due to my XP Home version of operating system? I can get XP Pro if I must or use my other computer that runs Vista . I see Vista is not included in your recommended software list.

Well I have the solution to my problem, thank you Scott.

..... make sure your system clock is not set for a
future time? In other words, make sure that your time zone is set
correctly, and that the current time and date displayed on your machine is
also correct. Ensure that it is not off by a year also.

My system clock was out by about 12hrs. After a reboot and re-entering the registration key all worked.
Everything seems to be running well now, and I can get into learning to use this software.
