Investment Studio > Setup > Subscription

Investment Studio requires two pieces of subscription information:

  1. your PIN (Personal Identification Number): a unique user ID assigned to you upon Investment Studio registration; and
  2. your subscription certificate: a time-limited file which, together with your PIN, enables Investment Studio on a specific computer for the duration of the subscription term.

While the PIN is permanent, the certificate expires at the end of the subscription term and must then be replaced. A new certificate is also needed if you move Investment Studio to a different computer or perform major system work like reinstalling Windows. A reasonable number of such "mid-term" certificate replacements is allowed. A large number of repeat certificate requests will cause the certificate server to block the PIN and flag the account for review and possible termination.

PINs and certificates are stored in the <DATA> directory. Different users sharing the same computer should therefore have separate <DATA> directories, each one containing a single user's PIN and certificate.

The subscription dialog

PIN and certificate validation are normally transparent processes. The subscription dialog is displayed only if a required piece of information is missing or if there is some other problem (e.g. if the subscription certificate has expired). The following screenshot highlights the dialog's key features:

Enter your PIN in the edit box in the dialog's upper left corner. Valid PINs consist of four groups of four alphanumeric characters (A-Z, a-z, 0-9).

PINs are case-sensitive: "A" is not the same as "a"! Use copy and paste to enter your PIN without typos.
Click Save PIN to write the contents of the PIN edit box (1) to disk. Closing the dialog with OK (8) also causes the PIN to be saved, along with the contents of the certificate editor (5). Neither button is enabled unless the PIN edit box contains a valid PIN.
Click E-mail request to create an e-mail message containing a request for a new Investment Studio certificate. The requested certificate will be tied to the PIN in the PIN edit box (1) and to the computer used to generate the request. The request will be sent to the certificate server using the computer's default e-mail client.

The requested certificate will be sent to the e-mail address currently on record for the specified PIN, i.e. not necessarily to the return address specified in the e-mail client.

If you wish to permanently change the e-mail address associated with your Investment Studio PIN, send an empty e-mail from the new address to

with your PIN (and nothing else!) in the Subject field. A confirmation request will be sent to the old e-mail address and must be answered for any changes to be carried out.

If your computer isn't set up with a default e-mail client, or if your default e-mail client doesn't support standard "mailto" syntax, nothing will happen. In this case, you can use Clip request (4) instead.

The E-mail request button is not enabled unless the PIN edit box contains a valid PIN.

Click Clip request to send a request for a new Investment Studio certificate to the Windows clipboard. The request can then be pasted into an e-mail client and sent to the certificate server, or pasted into a text editor (e.g. Notepad) and printed or saved to file. The requested certificate will be tied to the PIN in the PIN edit box (1) and to the computer used to generate the request.

The Clip request button is mainly useful if you are running Investment Studio on a computer without Internet access and therefore need to send the certificate request from a different computer. The request must be generated on the computer where the certificate will be used, but it can be sent to the certificate server from any computer.

A valid certificate request consists of a single line of text starting with the tag "<START>" and ending with the tag "<END>".

Example: <START>US-F71A-02B8-1DE6-21C1-E42B-EF56-A17C<END>

The entire line, including the start and end tags, must be included in the body of the request e-mail. Incomplete certificate requests will be ignored, as will any text outside the tags.

Certificate requests must be e-mailed to the address

Certificate requests sent to any other address will be ignored.

Certificate requests are handled by a mailbot. It doesn't understand comments, questions or anything else beyond the scope of properly formatted certificate requests, and will simply ignore all such communications.

The Clip request button is not enabled unless the PIN edit box contains a valid PIN.

Enter your certificate in the multiline editor below the request buttons (3, 4).

A valid certificate contains 45 lines of alphanumeric characters (A-Z, a-z, 0-9) enclosed between start and end tag lines ("<START>" and "<END>"). The entire text, including the start and end tags, must be entered into the editor.

Needless to say, nobody in his right mind would try to type in this mess manually. Use the clipboard: copy the text from your e-mail client (or from a text editor, e.g. Notepad, if you are transferring a certificate file received on another computer) and paste it into the editor.

Click Verify certificate to check the contents of the certificate editor (5). This can take a while, especially on older computers. Please be patient. A message box will eventually pop up and report the result. If the certificate is current and valid, you will see the following message:

Click Save certificate to write the contents of the certificate editor (5) to disk. Closing the dialog with OK (8) also causes the certificate to be saved, along with the contents of the PIN edit box (1). Neither button is enabled if an error was encountered upon certificate validation (6).
Click OK to save the contents of the PIN and certificate editors and close the dialog. To abort and close the dialog without saving, click instead.
