My Own Made 3D Fish Screen Saver Is Not Working Properly. What Is The Reason?

1st of all you should tell that in what software you have made your own designed 3D fish screen saver. If the animation of that software can be changed to the extension of .scr then you can apply your own 3D fish screen savers. Because in windows the valid extension for the screen savers is .scr and if you have saved your 3D fish screen saver with some other extension then your 3D fish screen saver might not work properly. To save your 3D fish screen saver with the desired extension follow these steps.Open the file of your 3D fish screen saver in software you have designed it.
Check whether it is running properly in the software or not.

Click on the file. A menu for the file options will open. Now click on the save as option. A dialogue box will be opened. In the lower corner of it there would be option for file name and save file as (available in most of the designing software.) Now save the file as all file and in the file name option, at the end of the name, write .scr.Now click on the save button. Now apply your 3D fish screen saver. It would be working well.
