SqlTools is an extremely light weight and fast windows frontend for Oracle. SQLTools++ is based on it with fixing some bugs. I started to use it from years ago in Windows XP era and love it much more than Oracle SQL Developer or Toad.

However, it requires Oracle Client installed. I always have installed Oracle Server for development at local, so this is not an issue to me.

About 3 years ago, I switched to Win 7 64bit and installed Oracle Server 64 bit for development. The SQLTools++ does not work any more with this error:

The application was unable to start correctly (0xc000007b).

Solution

  1. Download a 32bit Oracle Instant Client.

  2. Extract the Oracle Instant Client to a folder. E.g. d:\oracle\instantclient_12_1\.

  3. Add the folder into system PATH.

  4. Start SqlTools (or SqlTools++) again. It can be run up successfully.
