Hello,

You need to download Adobe eLearning Suite 6 trial from Adobe.com (https://www.adobe.com/cfusion/tdrc/index.cfm?product=elearning_suite)

Launch the installer for ELS 6, you will get 3 options :

Trial

Start Subscription

Serial Number

Choose Start Subscription and Sign in with your Adobe ID and password, your subscription for ELS 6 will start.

Thanks,

Vikram

Hello,

Do you have ELS 6 installed already on your computer (As a Trail) ?

If Yes : Uninstall ELS 6 Trial and launch the Installation again and choose "Start Subscription".

If No :

When you choose "Start Subscription" on ELS 6 installation, does it ask for Serial Number ?

Thanks,
Vikram

Hello,

ELS 6 suscription does not ask for Serial Number, as subscription works on your Adobe ID and password.

In your post you mentioned that you purchased ELS 2.5 subscription so it must be upgraded to ELS 6 subscription.

If you have ELS 6 installed on your computer (As a Trial), uninstall it and launch the installation again, choose "Start Subscription" (While installing ELS 6)

You can also share your contact information on tcssup@adobe.com, we will contact you.

Thanks,

Hello,

Your Welcome and I am glad that it fixed your problem

Uninstalling ELS 2.5 is purely your wish, as you can have different versions of Adobe product on your Computer (Except Adobe Acrobat)

Thanks,
