The Chart Window Won't Open

This may come about if you install ATM once, install either the same or different version again into a different location, then uninstall either of those. The error message maybe something like:

Exception of type 'System.Windows.Forms.AxHost+InvalidActiveXStateException' was thrown.

Here's what happens:

1. Install ATM - registers charting component
2. Install ATM again in a different directory - registers charting component
3. Uninstall either of those - unregisters charting component

You are now left with one installation of ATM, but the charting component is unregistered. All you have to do, is re-register it.

Click the Windows Start button at the lower left-hand corner of your screen. In XP and below, click "Run...". In Vista and above, search for "Run", then right-click on the "Run" icon and select "Run as administrator".

A little box appears.

Type or copy and paste the following, exactly, in the field in that little box:

REGSVR32 "c:\Program Files\Thinking Stuff\ATM v3.0.0\StockChartX.ocx"

The quotation marks are necessary. You may also need to alter the installation directory.

And then press the Enter key, or click the Ok button.

Now that's done, try to open the Charts window again. The fact that it opens at all is a sign of success. If it still does not work, check the directory is correct.
