Hello @afishetumomodu ,
This issue indicates that there is not enough free space on the C disk of your computer to install Revit 2023. As a solution, I recommend you to empty the C disk. First, you can start by deleting the files in the following places;
Temp Files: With all Autodesk software closed, navigate to the temp folder (type %TEMP% in Windows File Explorer and press Enter - or - C: Users\Username\AppData\Local\Temp), then delete as many files as possible.
Journal Files: The file path is located at, C: Users\Username\AppData\Local\Autodesk\Revit\Autodesk Revit <release>.
After making sure that there is enough space on the C disk, if the problem still persists, may recommend you to review the following;
