I am trying to download/install '3D Experience Catia for Students' however I am am experiencing an array of issues

First, 

I have bought the product, made an account, verified the email and am now following a guide within the 3D dashboard to download/install to my computer. 

1. I have added 'part design' to my favourite apps
2. I have clicked it and pressed download within the pop-up installation guide
3. I have opened the launcher it downloaded and followed instructions to finish the installation

Now I am stuck

1. Nothing else booted up, so i looked in my downloads, program files etc. and tried starting up every new app it downloaded to my system (Windows 11 Operating System)
2. None of the 'Troubleshooting' steps within the pop-up guide helped me as I couldnt perform what they were asking of me (for whatever reason)

3. Then i tried reinstalling 

   -> deleting the launcher from downloads, deleting the '3DExperience Launcher' Folder from Program files and reinstalling the launcher from the guide 

   -> After downloading and opening the launcher it asks me to click 'Next', then i am given the options to 'Repair' or 'Remove'. the option to 'Change' is there but it is greyed out.

   -> I click Repair (first i manually close all 3dexperience applications via Task Manager) and it pops-up with one of those windows application permission requests (like ' do you want this app to make changes to your device': the actual app name is something like a string of characters and then .msi) to which i click 'Allow'. Then it finishes 'repairing' and i click 'Finish' and the Launcher closes. Nothing happens after this (I waited 30 minutes for something to happen), the only thing i noticed from task manager is that the applications: '3DExperience Launcher Backbone', '3DExperience Launcher', and '3DExperience Launcher SysTray' start up, however as i said previously nothing happens, even if i close and open the apps again manually (I have also tried 'remove' and repeated the process and then repairing - to no avail)

    

   Secondly,

   I Submitted a 'Support Form' with something similar to what i have written above, when i clicked submit it brought me to an error screen that said something along the lines of 'You don't have access to this page' and 'Access Denied'. So i have no idea whether the support form went through or not, i have checked the email attached to my account and i have recieved no confirmation of anything (i checked spam/other mail aswell)

Another two things i noticed:

1. When I try to remove and reinstall i have to load the webpage up again from the link i was provided in an emil i receive after signing up. This is because when i go to click on 'Part Design' it comes up with a grey banner in the bottom left saying 'Unable to Retrieve Installation files'

2. Sometimes when i did this reinstall process it came up with this archaic looking permission pop-up asking whether this URL (it was the URL of my 3D dashboard) could link to the system/launcher or something like that. Here is the screenshot (i redacted the start of the URL just in case this is personal etc.):

   

Someone please help I need to start using this software this week and i need the downloaded version as the Uni has poor wifi in the building and don't want to rely on any 'online server' type product.
