"No CE Signature"
displays when downloaded
.exe file is run.
Problem: One of the Knitware programs is downloaded, but when the
downloaded file is double-clicked to run it and extract the files to be installed,
the "No CE Signature Found" error  occurs.

Cause: This error occurs when the downloaded file is corrupted, usually the
result of the download terminating before the entire file is downloaded.

Occasionally, this will happen if the Internet connection was disrupted during
the download. If this is the case, deleted whatever was downloaded and try
again when your connection is restored.

If you happen to still be using a dial-up connection to the Internet, that will
definitely interfere with the download, as most dial-up ISPs have restrictions
on the time or the amount of data that can be downloaded in a single
session. If this applies to you, call your dial-up ISP for assistance.

However,
the most common cause  of premature termination of the
download will be the security settings on your computer. These settings  exist
at multiple levels: Windows or Vista firewall, the security level that your
browser is set to, security level(s) within whatever security software you have
running on your system (e.g., Norton, McAfee, or the like). If you are running
McAfee, there is a "trust" setting in that program that is difficult to find, and
when found, seems not to be related. However, by having that trust setting
turned on, it seems to interfere with downloads from certain websites. McAfee
may or may not be the only security program with this type of setting. You
can turn off every security setting you can find, or experiment with them one
by one until you are able to complete the download successfully.

After each download attempt, check the size of the downloaded file.
If is not at least 4.6MB (will show as 4,668KB), then the download was
terminated prematurely and you cannot proceed. Once the download is
complete successfully, you can restore all security settings.

Note that if you cannot "save"/download the file successfully, you will not be
able to "run" it directly either.

Please consult the documentation for Windows, Vista, and/or your security
program for additional information on changing your security settings.
Something may have occurred during the download attempt.  There may
have been an intermittent problem with either the host server or your
connection. The demo file is 4.65MB and it should download in less than one
minute with a high-speed connection.   

If you still have a problem, you can purchase the demo CD. The CD
contains all three programs.  Once they are installed, no further download is
necessary, as each demo program can be activated to full program capability
with the serial number provided upon purchase of the full version.
