Dear sirs,

I'm would like to Upgrade my Step 7 v5.5 license to v5.7

I got an upgrade license "Upgrade from v5.3 -> v5.7"

When I select Upgrade in ALM it says "No matching upgrade license keys were found". Does that mean I can't use this upgrade license? Any way I could downgrade the v5.5 license to v5.3?

Thank you!
