Chempak Database Installation

AFT Arrow does not include the Chempak Fluid Library by default. The Chempak Database is a separate product that must be downloaded and installed as an addition to AFT Arrow to access the Chempak Fluid Library in the software.

Chempak File Location

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

When upgrading to a new version of AFT Arrow, you may receive a message that the database is outdated.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.
