Are you eligible for a complimentary (free) Lightroom 4 upgrade?

 
Adobe doesn’t notify customers who purchased single-user licenses about complimentary post-announce upgrades, BUT according to a somewhat obscure company policy, users who bought software (full or upgrade) soon after a new version was announced, might be eligible for a complimentary upgrade. If you followed my instructions on a previous post to purchase Lightroom 4 50% off, you might be one of the lucky ones.You need to contact Adobe directly to find out if you fall in the eligibility period. Let me know how it goes.

If you already purchased the upgrade and have questions about the installation, follow these simple steps here and here.
