I was facing same issue with error code "[FATAL] [INS-35955] The Database software home (C:\ORACLESOURCE) is already registered in the central inventory. This tool can only be used in a non-registered Database home."

Moved the setup to a different folder and tried installing. It worked.

Look into your %Program Files%\Oracle\Inventory\logs where you will find the reason for error.

I also encountered similar problem where I installed Oracle 18c XE,

Oracle Database 18c we are introduced to a new concept: Image Based Installation.

In Image Based Installation the Oracle Universal Installer of 18c takes the location of our setup.exe file and assigns it as its db_home location. That’s why before we start extracting the content of this file, we first need to decide where we want to create our db_home directory.

Mistake I made was I had the setup.exe in D://drive and for others location left as default(which is C:/ drive)

Solution:

  1. Copy and extract the entire folder which contain setup.exe in C:// Drive.
  2. Manually remove all the files in in C:/Program Files/Oracle (including Oracle folder)
  3. Run the setup.exe as Administrator
  4. Leave the other configuration paths as default

(Additional : Satisfy following condition when configuring the password

Oracle recommends the following guidelines when prompted for a password.

  • Contains at least one lowercase letter.
  • Contains at least one uppercase letter.
  • Contains at least one digit.
  • Is at least 8 characters in length.
  • Uses the database character set, which can include the underscore (_), dollar ($), and pound sign (#) characters.
  • Should not be an actual word.

You can find in your logs:

SEVERE:  [Jan 18, 2019 4:32:04 PM] [FATAL] [INS-35955] The Database software home 
(C:\ORACLESOURCE) is already registered in the central inventory. This tool can only be 
used in a non-registered Database home.
ACTION: Choose a different location as Oracle home.

Try install Oracle in another directory.
