Install Daqarta License Key

Controls: File Menu >> Install License Key

If you purchase Daqarta you will be sent a small encrypted RegUser.ASK text file as an Email attachment. Open this attachment; there will be a line of identifying text starting with "Daqarta32TextID:", followed by a large block of seemingly-random alphanumeric characters.

Copy everything to the Windows clipboard. To do this you first select (highlight) the text by left-clicking on the very first character ("D") and holding the mouse button down as you move the mouse to the end of the attachment. Note: Since the text block is so large, this may involve scrolling beyond the bottom of your Email display window. Then hit CTRL+C to copy the selection to the clipboard.

Some Email systems may eliminate the separate RegUser.ASK attachment and append its contents to the main message. If that happens, just copy the entire message to the clipboard.

Now open Daqarta and click on the Install Daqarta License Key option in the File menu. A dialog will open containing a large text entry field; use CTRL+V to paste the clipboard contents there, then hit the OK button. Daqarta will extract the key data and save it as a binary file that it will find the next time Daqarta starts up.

This key file will enable all Daqarta features for your license level (Professional or Personal / Hobby), and it will continue to work with all future Daqarta versions; you only need to pay once. Personal / Hobby licenses may be upgraded to Professional by paying the price difference (currently US $70.00).
