These 2502 and 2503 errors are because a program needs to install using the temp folders and they do not have permission to do so. I have been doing IT for 35+ years.
These next steps give permissions to the temp folder to fix not having those errors.
Press the Windows key on the keyboard and while holding that key down, press the letter "R"
The Run command will display
type cmd
Hold the control key + the shift key and while holding both of those keys, use the mouse to click the OK button
Answer Yes if you are prompted with a Yes/No question
copy and paste these commands
takeown /f "%systemroot%\Temp" /R /A /D Y
icacls "%systemroot%\Temp" /inheritance:r /grant:r Users:(OI)(CI)F /T
icacls "%systemroot%\Temp" /inheritance:r /grant:r Everyone:(OI)(CI)F /T
icacls "%systemroot%\Temp" /grant Administrators:F /T
icacls "%systemroot%\Temp" /grant Users:F /T
icacls "%systemroot%\Temp" /grant SYSTEM:F /T
icacls "%systemroot%\Temp" /grant Everyone:F /T
takeown /f "%temp%" /R /A /D Y
icacls "%temp%" /inheritance:r /grant:r Users:(OI)(CI)F /T
icacls "%temp%" /inheritance:r /grant:r Everyone:(OI)(CI)F /T
icacls "%temp%" /grant Administrators:F /T
icacls "%temp%" /grant Users:F /T
icacls "%temp%" /grant SYSTEM:F /T
icacls "%temp%" /grant Everyone:F /T
Done. No reboot necessary.
