How to activate Sothink products after purchasing?

To activate your purchased Sothink product(s) is a no-sweat process. You can do it in just a few steps specified as following:

Step 1: Download and Install Sothink Quick Launcher

Regardless of what Sothink product(s) you have purchased, to activate it, you must first download and install the Sothink Quick Launcher, which is available at:

Step 2: Create an Account at Sothink Member Center

Similar to step 1, no matter what Sothink product(s) you have purchased, you are supposed to create an account at Sothink Member Center immediately after receiving the e-mail receipt, from where, you can click the provided link to create your Sothink membership.

Step 3: Activate Sothink Product(s)

After finishing the previous two steps, you are now about to activate your purchased Sothink product(s). Just click on the desk shortcut of Sothink Quick Launcher, you will see an “Activate” button at the bottom right corner, click on it, and then enter the e-mail and password you set up at step 2, click the “Activate” button again to finish the activation process.


In theory, you will have to do the activation process only once regardless of how many Sothink products you purchase. However, if you buy another product in the future, you will have to redo the activation and, if you have been using the product under offline status for over 30 days, you will be required to re-verify your membership.
