This brief shows you how to activate HPA (a High Priority Access support and maintenance service) for an MPLAB® XC compiler after having received a printed copy of the activation details. You will need to follow these steps if you renewed your HPA via a third party vendor and you received the activation details on paper or as a digital file, or you selected the physical media option when purchasing HPA renewal in MicrochipDIRECT.

The following steps assume that your compiler has already been registered with a mySoftware account.
  1. Login to the mySoftware account with which the compiler is registered. There are three ways you can do this.
    1. Navigate to the www.microchip.com/mysoftware website in your favorite web browser. Use your regular Microchip Direct credentials to log in when prompted.
    2. If you are already logged in to your myMicrochip account (www.microchip.com) in your web browser, you can get to your mySoftware account by selecting Registered Development Tools from the myMicrochip pull-down menu, as shown in the image below.
    3. From the MPLAB X IDE application, go to the Start Page tab. If this tab is not visible, open it using the Help > Start Page menu item. Click MY MPLAB X IDE, then use your regular Microchip Direct credentials in the E-mail Address and Password fields to log in, as indicated below.
      On the page that opens, click the View My Development Tools link.
  2. Click the Apply MPLAB Software HPA link in the left tool bar. This will open the following page.
  3. Enter the 16-digit HPA activation key you received in the renewal document into the HPA Activation key field. Do not enter the activation key for the compiler, shown in the list of registered tools under My Software.
  4. Select the relevant MPLAB XC compiler from the Select Software to Renew drop-down menu.
  5. Click the Renew button. This activates the compiler's HPA. You next need to ensure the compiler is using a license file that reflects these changes.
  6. Click the My Software link shown on the left, under My Development Tools.
  7. For the compiler you selected in step (4), download the updated license file(s) for the relevant host ID(s).
  8. Install (run) the license file(s) on the matching host machine(s).
