Purchase Protection Only
If you only need Protection without the many benefits of Automation, you can purchase one of our licensing clients and manually manage customers, licenses and activations.
The truth is, most of our customers choose to save time and money by using the SOLO Server Automation features and services included in our monthly service plans. Not only does it count and limit the activations for each license, it also saves time, gives you more control and provides customers the immediate gratification they are looking for, with features like:
- Automated license activation 24/7/365
- Customer self-service portal to see and manage licenses
- Periodic license validation
- New version notification
- License revocation
- Automated license transfer to another computer

Software Maintenance
Each license of our software comes with one year of software maintenance, which includes updates and electronic support. This maintenance is renewable at any time, and is optional.
Annual maintenance renewals cost roughly 20% of the license cost.
Be sure to keep a safe archive of the installation media for the version that you purchased and are using in your software. Only the latest version is kept on our website and only for customers with an active maintenance agreement.

Very happy to extend our licensing system to include Android and Linux platforms
Our company provides barcode decoding and barcode authentication software for Auto ID industry.
The license activation feature is by far my favorite feature. We have used Protection PLUS 4 and Instant Protection PLUS 3 for many years, but after the release of Protection PLUS 5 we like it even more because it allowed us to extend this activation/licensing system to Android and Linux platforms.
By automating license activation we have saved a lot of time for ourselves and - most importantly - improved our product offering for our customers.
Do not hesitate with SoftwareKey - it's a solid company, great competitive products and outstanding customer support.
