Updating to Service Pack 14980 - Space error

I have SD Plus on-prem installed on Win2022. Tried to install Service Pack 14980 today. It advised there wasn't enough disk space (there was 2gb free). Its a virtual server so I added 4gb. Got the same error. When up to 10gb free. Still get the same error. Not sure what to try.
