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.
