Background of writing this article
In RAD Studio's Data Explorer, I got an error that FireDAC's InterBase settings could not be written to a file, and I couldn't test the EMS server.
Here is a summary of the process up to the resolution.
Cause and solution
I mistakenly installed InterBase twice and deleted the latest one was the cause of the failure ...
There are two causes.
- The environment variable setting has been rewritten → Instance has a license error
- The registry setting has been rewritten → Access rights to the referenced folder are required
Here are the steps to fix:
- Open RAD Studio
- Tools> Options menu
- Select the "Environment Options | Environment Variables" node
- Change the following two "user environment variables" to appropriate values
- IB_Protocol Specify the InterBase server instance name
- InterBase – Specify the directory where the InterBase server executable file is located
Open the registry editor from "Run with a specified file name (Win + R)" (regedit)
Open the "HKEY_CURRENT_USER \ Software \ Embarcadero \ FireDAC" key Change the following two strings to appropriate values
C: \ Users \ Public \ Documents \ Embarcadero \ Studio \ FireDAC \ FDConnectionsDefs.ini
C: \ Users \ Public \ Documents \ Embarcadero \ Studio \ FireDAC \ FDDrivers.ini
Troubleshooting is difficult.
Thank you for the person inside (Mr. Y Sawa).
