The following issue occurs if you have had Toad 12.0, then uninstalled it, and following that installed 12.1.
If you launch Toad 12.1 and go to Utilities | Copy User Settings, and choose the User Files from the uninstalled folder: e.g.
C:\Users\admin\AppData\Roaming\Quest Software\Toad for Oracle\12.0_uninstalled, the files are imported ok, but as the 12.0 version had been uninstalled, there are many incorrect paths in the Toad.ini file which cause several things in Toad 12.1 to not work, such as creating database objects within the schema browser.
An example of the error shown is:
'File C:\Users\admin\AppData\Roaming\Quest Software\Toad for Oracle\12.0\User Files\NEWPROC.sql for PROCEDURE not found'
The reason for this is that due to the nature of Toad 12.0 being uninstalled, but Toad 12.1 is still using the uninstalled User Files, there are many incorrect paths inside the Toad.ini file. For example:
[PLSQLTEMPLATES]
PROCEDURE:Default=C:\Users\admin\AppData\Roaming\Quest Software\Toad for Oracle\12.0\User Files\NEWPROC.SQL
FUNCTION:Default=C:\Users\admin\AppData\Roaming\Quest Software\Toad for Oracle\12.0\User Files\NEWFUNC.SQL
TRIGGER:Default=C:\Users\admin\AppData\Roaming\Quest Software\Toad for Oracle\12.0\User Files\NEWTRIG.SQL
PACKAGE:Default=C:\Users\admin\AppData\Roaming\Quest Software\Toad for Oracle\12.0\User Files\NewPackage.SQL
PACKAGE BODY:Default=C:\Users\admin\AppData\Roaming\Quest Software\Toad for Oracle\12.0\User Files\NewPackageBody.SQL
TYPE:Default=C:\Users\admin\AppData\Roaming\Quest Software\Toad for Oracle\12.0\User Files\NewType.SQL
TYPE BODY:Default=C:\Users\admin\AppData\Roaming\Quest Software\Toad for Oracle\12.0\User Files\NewTypeBody.SQL
WORKAROUND:
Amend the incorrect paths in the Toad.ini file, or either create a new User Files folder
STATUS:
Waiting for fix in a future release of Toad for Oracle
