title: Oracle DB Client 19c install error -> INS-32103 Specified Oracle Home user does not match with existing Home user
body: <p>I am trying to install Oracle Database Client 19c. From what I understand, if I want to connect SQL Server Management Studio to an Oracle database, I need to install this client. So I already installed the &quot;Instant Client&quot; without any problems. I was able to test the connection under the &quot;ODBC -&gt; Oracle driver&quot;</p>

  <p>Below are my installation steps of the Database client</p>
  <ol>
  <li>select &quot;Administrator&quot;

  <li>For selecting a Home User, I've tried using an Existing Windows user (local user), and also I've tried &quot;Use Windows Built-in Account&quot;

  <li>I selected the Oracle base and software location. Then I clicked &quot;Next&quot; and it gives me the error about the Home User does not match with existing Home user.
