The Installer is Unable to Instantiate the File key_xe.reg file

  • When I attempt to install the Oracle Database XE 11g. 
      • “The installer is unable to instantiate the file C:\Users\ … … \KEY_XE.reg. This file does not appear to exist.”  
  • With the error message box still open, click the Windows start button and type “regedit” in the search box. Press enter. The registry editor will open.
  • On the left column, expand the folders as follows: 
      • HKEY_CLASSES_ROOT -> Installer -> Products -> 266B7A….. -> SourceList-> Media
  • Look for ’1′ under Name on the right column. Under ‘Data’ on the same row, the value should be ‘DISK 1′ or something similar. Right click on that row and click on ‘Modify’.
  • A window named ‘Edit String’ will open and type in the address indicated in the error window you had from the Oracle installer, ending just before ‘KEY_XE.reg’. It should end with a row of numbers/letters then ‘}\”.
  • Click OK and close the Registry Editor.
  • Return to the Oracle Installer and click OK on the error message box.
  • It will take a while, but eventually, the installer will indicate that installation is complete.
  • To check if everything’s good, click on the windows start button -> All programs -> Oracle Database 11g Express Edition -> Get started.
  • A web browser will appear and the Oracle Database Get Started page will load.
