In this guide, we assume that you have installed PrimoCache on your computer. If you haven't done that already, check out the Download and Installation pages. PrimoCache contains a built-in evaluation license for a free 30-day trial with full functionality when it is first installed on a computer. If you enjoy the trial and would like to permanently activate PrimoCache, check out the Purchase page and buy an appropriate license.
After you get a PrimoCache license, follow the steps below to activate and license your copy of PrimoCache (version 3.0.9 or later). If you use PrimoCache 3.0.2 or an earlier version, click here for instructions.
Step 1. Open PrimoCache and click on the Activate PrimoCache icon button in the toolbar at the top of GUI window. The activation dialog will pop up.
Step 2. There are two ways to activate the software: Online Activation and Offline Activation. If you have access to the Internet, go to the Step 2-a. Otherwise, go to the Step 2-b.
Step 2-a. Online Activation
Choose Activate over the Internet. Enter your user name and activation code which you received from the license email. Then click Activate.
Alternatively, Step 2-b. Offline Activation
If you are on a computer without internet access, you may use the offline activation. However, this way takes some time.
1) Copy your Product ID and email it to us (Customer Support). You will receive a key file for this product ID within one business day.
2) After you get the key file, choose Activate with a license key file.
3) Click Browse to navigate to the key file.
4) Click Activate.
Step 3. Please wait while the software installs your license. After the license is successfully installed, you will see the message below. Restart the computer to finally activate the software.
Step 4. Now verify the activation result. If PrimoCache is successfully activated, you will see Registered in the title bar of the software.
Extend PrimoCache Trial Period
If you haven't bought a license of PrimoCache but have an extend trial key file, you may follow the steps below to extend your trial period of PrimoCache. The process to extend the trial period is almost same as doing offline activation.
Step 1. Click on the 
icon button in the command toolbar to show the activation dialog.
Step 2. Choose Activate with a license key file. Then click Browse to navigate to the trial key file you got. And then click Activate.
Step 3. Wait while the software installs your trial license until you see a message telling the results. If the trial license is successfully installed, you will be prompted to restart the computer.
Step 4. Now restart the computer to apply this trial license key. You will see the new trial period after reboot.
