Upgrade instructions

Download the Associate Engine .zip distribution file and unzip it into a temporary directory on your computer, such as into c:\ae
Upload ae.pl to your webserver's cgi-bin directory (or to whatever directory you normally put script in). Note: If necessary, edit the first line so it indicates where Perl is on your server; default is #!/usr/local/bin/perl Note: Be sure to upload in ASCII mode and set the file permissions (i.e.: CHMOD 755 which is rwxr-xr-x).
Get an AWS Access Key from Amazon.com.
After upgrading, you may encounter one of these errors:
- No output or "Internal Server Error"
  
  If you find that ae.pl stops working after an upgrade (either you see "500 Internal Server Error" or nothing shows up because you're using <script> or SSI tags), then the first thing to always do is re-upload ae.pl in ASCII mode and then re-enable the execute permissions (CHMOD). This is the most common upgrade problem. See solutions.
- "Request has expired. Timestamp date is ..."
  
  This error means that your server's clock is too far off of the correct time. Ensure that your server's clock is within 15 minutes of the correct time otherwise ae.pl will report this fatal error. This time accuracy is a requirement of Amazon.com web services. To compare the time from your server's clock with the time from an atomic clock, access your AE Configration Report (ae.pl?cfg=CFGVALUE). If you don't have administrator privileges to adjust your server's clock, then set the configuration variable clock.offset to offset the clock (e.g.: "10" to offset the clock forward by 10 seconds, "-10" to offset the clock back by 10 seconds).
- "Perl module 'Digest::SHA' is not installed."
  
  This error means that the Perl module "Digest:SHA" is not installed. Contact your hosting company to install the module. Alternatively, look in the .zip file and upload the entire "Digest" directory (as a whole) to the directory where ae.pl is located. So if ae.pl is in cgi-bin then you should end up with cgi-bin/Digest/SHA/PurePerl.pm

NOTE: This update is required.

Fix: Uses affiliate's AWS Access Key.

Uses affiliate's AWS Access Key to access Amazon.com's AWS (Amazon Web Services). Get an AWS Access Key from Amazon.com then enter it into your ae-ini.txt configuration file. If you do not enter your own AWS Access Key, Associate Engine uses a default AWS Access Key that may occasionally cause Associate Engine to return "No results found".

Prior to this point was Associate Engine v10.08.25.
