The isr file extension is associated with InstallShield, a Microsoft Windows program for creating software installation packages.
An isr file stores information that InstallShield uses when uninstalling an installed program. It is typically created as _deisreg.isr alongside other files belonging to the installation.
This is an internal text-based data file for InstallShield rather than a document intended for regular editing.
An isr file can be viewed in any text editor, such as Windows Notepad. The contents are intended for InstallShield, so editing the file manually may affect the associated program's uninstall process.

The ISR file extension is used by Go-Moku computer game files. These files store information about a Go-Moku game.
ISR files are application-specific and are intended to be handled by the Go-Moku software that created them.
Open an ISR file with the Go-Moku game associated with it. Use the game's Open or Load command, if available, rather than opening the file in a text editor.
If Go-Moku is not installed or the file came from a different version of the game, the file may not open correctly.
There is no standard conversion format for Go-Moku ISR files. If the game provides an export option, use it to create a different representation of the game.
Otherwise, keep the file in its original format for use with Go-Moku.
