The easiest way to install GroIMP is to run an executable file. The file will also automatically create a shortcut.

GroIMP is written in Java, which means it should follow Java's WORA-principle (Write Once, Run Anywhere) and should run on every Java-capable platform. GroIMP has been tested successfully on Unix and Windows platforms.

GroIMP 2.1.7 requires the installation of a Java runtime environment of version 17. This can be obtained from Oracle at www.oracle.com.

For a reasonably performant runtime behavior, at least 256 MB RAM and a 1 GHz processor are recommended.

GroIMP installation executable are available on the grogra website and on the gitlab release section as a zip-file, windows exe, or debian release.

The windows exe and debian release are executable files that will extract and install GroIMP on your computer. It will also provide you with the possibility to create a menu entry and a shortcut. Mac users need to download the zip-file, extract it and run GroIMP from the command line.

The directory structure of the zip-file has to be preserved, check that your zip program is set up accordingly (and does not extract all files into one and the same directory).

After extraction of the zip-file, the following files, among others, are present in the installation directory:

`README`

This plain text file contains additional information about the GroIMP distribution. Please read it carefully.

`INSTALL`

This plain text file contains instructions for the installation of the GroIMP distribution, legal notices and other information. Please read it carefully. If you have trouble with the installation procedure described in this manual, please consult the file `INSTALL` a solution.

`plugins`

This directory contains all the plugins that are part of the binary distribution of GroIMP.

`core.jar`

This file is an executable java archive and the entry-point for the Java runtime environment to start the GroIMP application.
