When I select View | Formatter options in Toad's menu, I get an error message and the formatter options do not open. Also, if I double click on the fmtoptions.exe file, in the Toad for Oracle 10 folder, I get the same error.
The exact error can differ from machine to machine.
1) Close Toad for Oracle.
2) Rename the FmtOptions.exe file, located in the C:Program Files\Quest Software\Toad for Oracle 10 folder, to FmtOptions.exe.old.
3) Place the FmtOptions.exe file that is attached to this solution in your Toad for Oracle 10 folder.
4) Launch Toad and selecting View | Formatter Options.
5) Without closing Toad, remove the FmtOptions.exe file you put in your Toad for Oracle 10 folder and rename the FmtOptions.exe.old back to FmtOptions.exe.
Waiting for fix to be released in a future version of Toad for Oracle.
