# Evaluations

### After I purchase a license, do I need to reinstall the software?

There is no need to reinstall the application after the purchase of a commercial license for the on-premise/server product version. In order to upgrade the license from trial to the full one, you have to reactivate the license to apply for an extended period of software validity.

### Can I evaluate a product for free before purchasing it?

Yes, you can try our cloud services free for 14 days and the self-hosted version for 30 days. To obtain an evaluation copy, register for [a trial version](https://wproofreader.com/sdk#pricing) on our website.

### How do I extend my server product evaluation?

We generally do not extend the evaluation period for our products. The 14-day trial for cloud services and 30-day trial for the on-premise version are designed to provide sufficient time for testing and integrating WebSpellChecker products. However, extended evaluation periods are available for an additional fee, depending on the desired duration.
