Why Your v2 Code Doesn't Work with v3

Technical Explanation

JPEGmini v2 and v3/v4 are completely different products:

  • Different codebase

  • Different licensing system

  • Different activation servers

  • Different feature sets

Think of it like:

  • ❌ Using a Windows 10 key to activate Windows 11

  • ❌ Using Office 2016 key for Office 365

  • ✅ You need a new key for the new product

What Happens If You Try?

If you enter your v2 activation code in v3/v4, you'll see:

Error: "Invalid activation code"

This is normal! Your v2 code is valid - it just doesn't work with v3/v4.

Licensing Model Change

1-year updates

Pay once, updates forever

Pay once, updates for 1 year

Code format: 20 characters

Code format: 25 characters

Example: XXXXX-XXXXX-XXXXX-XXXXX

Why the change?

  • Sustainable development model

  • Regular feature updates

  • Better support

  • Optional renewals (app still works after expiration)

Can I Transfer My v2 License?

No. v2 licenses cannot be "converted" to v3:

  • ❌ No automatic upgrade

  • ❌ No license transfer

  • ✅ Must purchase upgrade at special pricing

But: You keep your v2 license! You can use both versions.
