I can't find the Installation ID for an Offline deactivation

Question

Hello, 
 I've a 2019 freelance license and I'm struggling to deactivate it from my laptop and reactivate it on my PC. This is the second time I'm trying to get some help. I've got this message from the RWS Support: 
 I can confirm that the license has been reset and it is available in your account.

The 2019 version no longer supports the ONLINE activation/deactivation process. Please use th OFFLINE instructions on how to activate/deactivate the license: https://gateway.sdl.com/apex/communityknowledge?articleName=000001383

Please let me know if you require further assistance in this matter, otherwise the request will be closed in 24 hours.

Regards,
Monica ....I've found the page but I CAN'T FIND MY INSTALLATION ID (which I need it for the offline deactivation)...CAN YOU PLEASE, TELL ME WHERE CAN I FIND IT? THANKS A LOT Silvia Mestre

Hi Silvia Mestre 
 Your Support case is still open and the RWS technician will help you through that case. There`s no point opening new threads here is we already opened a case for you. 
 Thank you, 
 Sorin

Hi Mark Everson 
 Please try to reset the license from your RWS account as described in this article: https://gateway.sdl.com/apex/communityknowledge?articleName=000001616 
 If it doesn`t work, open a new thread for this and I`ll raise a support ticket for you to have your license reset. 
 Thank you, Sorin
