Frequently Asked Questions
OCCT's licensing model is straightforward: Personal users need one license per household and Pro/Enterprise users need one license per platform (Windows/Linux) for their whole company. There is no limit on the number of concurrent instances or the number of computers you can test (although number of cloud uploads depend on your license type). Please note though that sharing or redistributing your license outside of your household or company is strictly prohibited.
OCCT licenses are platform-specific, so a Windows license does not grant access to the Linux version. However, you can add the Linux version at a discounted price.
