Any time you have 5 or more licenses of the same version, you can batch assign them to your end users.
You will need to prepare a CSV file listing each assignee. In columns A, list the email addresses of your users. The upload will not work without this. You also have the option to add names: first names are placed in column B and last names in column C. 

Step 1: Open My Products.

• Go to our website.
• Click on your name to open the account dropdown.
• Select My Products.

Step 2: Assign to multiple users.

• Click the arrow to expand the product you want to assign.
• Click the arrow next to Unassigned Licenses.
• Choose the Assign to multiple users.

There will be a popup prompting you to upload your CSV file.

• Click on Browse.
• Choose your file.

The window will now reload showing the data from your CSV file.

• Using the check boxes, you can unselect any users that should not receive a license.
• Once you are ready, click on Select.

The window will update displaying the status of each assignment. A green circle will appear next to each successful assignment. An orange triangle will indicate an error, hover your mouse over it see the reason of the error.

• Click on Ok.

Step 3: Check Assignment.

• Expand your product.
• Check for errors.

Keep in mind, if there were any errors, you will need to reassign that license.
