Microsoft Office professional plus 2019 - reinstallation help required.

Hi,

I bought Microsoft Office Professional plus 2019, in 2019, and installed it on my computer.

I have now purchased a new computer due to my previous computer crashing beyond repair. To give you an understanding of the extent of the issue, I am only able to gain access to my previous computer by loading the DOS prompt in safe mode, as the password doesn't work any more, and I am unable to move around the drives on the computer to find any files without using Notepad.

After talking to Intel and Microsoft I tried and failed to access information about the computer to find out what driver could be at fault and they said they could not help me any further.

I am unable to uninstall Microsoft office as I can't run any programs on the computer and this is the reason for purchasing a new computer. I will be trying to access the hard drive with a docking station at a later date to try and retrieve the lost files.

I have tried to install Microsoft office on my new computer however as I bought I through a website and not the Microsoft Office store i think it is having issues finding the code that relates to it!,

When trying the start my subscription and entering the product key, a message comes up the says service unavailable we are having technical issues try again later.

Is there a way I can install my bought Microsoft office on my new computer ?

Thanks,
