Maple ships with its own copy of the JRE to use, independent of the system version. You can change this manually, although we recommend using version 8:
- Download and install the latest version of JRE 8.
- Make sure that you install the one with the same architecture (32-bit or 64-bit) as Maple.
Note: You may need to use an older version of the JRE instead - 8u144 has worked well in the past, but others are needed in some situations.
If you are downloading a JRE file from the older version link you don't need to install it. Just copy the whole folder (once extracted) to the Maple directory and rename it to jre.
- On Windows, copy the new "JRE" folder (which will have a name of the form "jre###") from where you installed Java, and then and paste it into the appropriate Maple folder below.
On Linux, you can extract to the appropriate Maple folder.
Example JRE folders on Windows:
C:\Program Files\Java\jre1.8.0_144 C:\Program Files (x86)\Java\jre1.8.0_144
Maple folders on Windows:
C:\Program Files\Maple 2019 C:\Program Files (x86)\Maple 2019
Maple folders on Linux:
Rename Maple's original "jre" folder to "jre.old".
Rename the "jre###" folder to "jre".
Once the Maple folder looks like the image below, try to launch Maple again.
