I'm getting errors when Installing ChurchTrac or Program Updates

You may encounter one or more of the following errors when trying to install ChurchTrac or a program update:

CRC failed in StartAccess_2002.exe
Unexpected end of archive

or

CRC failed in ctapp6.mde
Unexpected end of archive

or

Some installation files are corrupt.
Please download a fresh copy and retry the installation.

Also, you may continue to get this error, even when trying to download the update multiple times. After running an update and receiving this error, you may be unable to open ChurchTrac.

These errors are caused by a corrupted update file that you have downloaded. This usually happens because the download was interrupted before it could complete. This type of error is more common on dial-up or wireless internet connections, as they are more susceptible to dropping the connection or encountering interference. If the signal or internet connection is lost, even for a moment, it could cause the download to become corrupted.

Internet browsers, like Internet Explorer, typically store a local copy of the websites and files you download, in case you visit the site frequently or attempt to download the file again in the future. Browsers do this because it is much faster to open a locally-stored webpage or file than it is to download it again from the web. Unfortunately, if it downloads a corrupt file the first time, it may continue to "download" the same corrupt file from the browser's locally stored temporary files instead of going back to the website to get a fresh copy of the download. To correct this problem, you first need to delete the temporary internet files that your browser is storing, and then try the download again.

To delete the temporary files, open Internet Explorer (these instructions are for Internet Explorer 6/7, but if you use a different browser, the steps should be very similar).

Click on the Tools menu, then select Internet Options. This will open the Internet Options window.

On the General tab, click the "Delete..." or "Delete Files..." button, then continue the process to delete the Temporary Internet Files. If your browser has a lot of temporary files, this process make take several minutes. You do not have to delete your browser's cookies, history or other data.

When the temporary files have been removed, restart Internet Explorer and try the download again.

Note: if you are using a dial-up connection, make sure there is no noise or interference on the line. If so, switch to a different line. If you are using a wireless connection, move closer to the router or wireless modem so you have a better signal, or connect using a wired connection instead.
