Download UltraCorr-X

We strongly recommend that you use either Google Chrome or the Firefox browser to download our database because Microsoft Edge tries to change the filename.

Some early users found our original delivery method for delivering UltraCorr-X rather cumbersome as it involved downloading multiple files and receiving one by email.

We are now using an improved download process for our new version, UltraCorr-X version 2. You only have to download one file, an encrypted ChessBase archive (CBZ file) of about 208MB in size.

This is like an ordinary CBV archive except that it is password protected. It will not open without the password which will be emailed to you after we receive PayPal's notification of your payment. The password will normally be sent to you within an hour or two, unless we are asleep or out of the house in which case there could be a delay of few hours.

You can either pay first or download first and pay afterwards.

The CBZ file contains all the separate files of the database and within a couple of minutes of entering the password you will have a functioning UltraCorr-X database.

In Windows, right-click on the link below and select the destination folder for the database on your computer hard drive. It is probably best to create a new folder for it.


Once you have downloaded the CBZ file, we recommend keeping a copy of that on a backup resource, such as a USB, in case you have any problems later.
