If you have version 2.04 or older of CATS and update to version 8.0 of RATS, you will need updates to some of the CATS source files for compatibility with RATS 8. These files are provided in the zip file linked below. Just download the file and extract the contents into your existing CATS directory (usually C:\CATS2), replacing the existing files.
If your CATS CD is older than version 2.04 (see the label printed on the CD), you may also need updates to other files. If so, please contact us at
support@estima.com
Be sure to include your full name and your RATS and/or CATS serial number.
