Failed to activate software license: Invalid Parameter {501}

Where do I see this message:

This message will be a line entry in the Authorization Log. 

What does this mean:

Case A: This indicates a typo in the activation code.

Case B: This indicates that the default software license file is not correct. In this case the message is preceded by the line "Missing product key: StatusOk". Below is an example of the relevant section of the authorization log:

9/27/2013 3:04:08 PM ----ENTER CODE----

9/27/2013 3:04:08 PM WRITE AUTHORIZATION - SVSlope

9/27/2013 3:04:08 PM Missing product key: StatusOk

9/27/2013 3:04:08 PM Failed to activate software license: InvalidParameter {501}

9/27/2013 3:04:08 PM License server reported: StatusOk {0}

What should you try:

Case A: Check to see that the code was typed correctly in the the authorization field.  Sometimes copying and pasting will change a digit in the code or a capitalization.

Case B: Re-install the latest version of SVOffice2009. Ensure the option to install the HASP drivers is selected. A computer restart may also be required.

Open a web browser and visit the URL http://localhost:1947/. This is a diagnostic page that lists the authorization keys available to your computer. If this page is missing, then do you not have the latest drivers installed. (See:Where do I get the latest usb key drivers)

If this page opens up, click on the Administration Option (left-hand side of screen) and click on HASP keys.

When plugged into your local computer, a listing in the table  with Key Type = HASP SL Legacy  will be present  if the default software license is correct, similar to this:
