Chempak Database Installation

AFT xStream does not include the Chempak Database by default. The Chempak Database is a separate product that must be downloaded and installed as an addition to AFT xStream.

Database File Location

The Chempak Database is installed in C:\AFT Products\Chempak Data\ by default. If both AFT xStream and Chempak Database are installed to their default locations, no further configuration is necessary. However, if AFT xStream or the Chempak Database are not installed in a default location, AFT xStream will need to know where to look for the Chempak Database. This is specified in the control.aft file, located in the same folder as xStream.exe. If the files cannot be found the following message is displayed:

Control.aft can be edited with a text editor, and by default looks like:

If the Chempak Database was installed to a location other than the default, the line "ChempakDataPath = " will need to be edited to include the directory it was installed to. For example: "ChempakDataPath = C:\My AFT Files\Chempak Data"

Upgrading Chempak Database Version

If you had Chempak installed with other AFT products, you may receive a message that the library is outdated.

To fix this issue, download the newest version of the Chempak Database from the AFT website. Be sure to install to the same location as the existing Chempak Database, and double check the control.aft file if necessary.
