Hi Serena Valentino

You don't need to deactivate the 2019 version via the Help tab activation link in Studio 2019.

 Instead, follow the instructions provided by Steven Whale here:

How to install Studio 2019 and 2021 side by side

(Edited)

For anyone else finding this thread in future, who really does want to deactivate Studio, follow this procedure:

Click on the 'Licensing and Installation Assistance' dialog bottom left of your screen:

That will open up an Online Chat box:

Click on 'Reset License'

All the best, 

Ali 

Thanks Ali, good to know!

I thought it was necessary to deactivate one version to use the other. Thank you for you precious help. 

Nice day

Serena

Sorry Ali, i have just tried to upgrade the programme (following the procedure indicated), so i went in my account and try to download the upgrade available, but this failed and the following message appeared: 

In order to process this upgrade, please return any in use activations.

I think it is related to the deactivation of the previous version..

What do you think?

Thank you so much!

Hi Serena Valentino

I was going on the information provided by here:

How to install Studio 2019 and 2021 side by side

Now I would recommend going here:

Licensing & Installation problems

The above link will take you here:

Then click on 'Reset License', select your license type and take it from there.

If that doesn't work, try filling in the following form:

Unless you have a Professional Network version, I think you can run 2019 on your 2021 license, but I think you will still have to deactivate the old one in order to activate the new one.

Hi Daniel Hug &  Serena Valentino

Yes, but not by releasing it via the Studio software but rather by doing the following:

I think Serena's setup has a fault that is preventing her from being able to follow the instructions given by  here:

How to install Studio 2019 and 2021 side by side

Perhaps Denise Baldwin  can help?

All the best,

Hello Serena Valentino Alison Field ,

The problem here is the license simply hasn't been 'upgraded as follows

Once this is done, then all should run smoothly.

Aha! Problem solved!!!

Thanks,

Ali

Hallo Steven, thanks for your kind reply. Indeed, I have clicked that banner and it was ok. After that, a blue banner appeared on the left (Upgrade1) and when I click this banner the folloqing message appears: 

In order to process this upgrade, please return any in use activations.

So, it doesn't work... 

My initial problem is that a have troubles when I try to deactivate the 2019 version, as I get the following error message: 

Error 143 Failure in accessing the license or persistaence in store.

Do you have an idea of how I could solve this problem?

Thank you so much, 

Serena
