Anyone having trouble launching the installer with java even though you have java installed, you can run them in a .bat file. To do this you have to go to desktop, right click on an open space, then click new file. Rename the file aristois.bat then right click the file and select edit. Then edit the file in note pad.
Then use this code. java -jar {Full file location here}
.
For example, java -jar C:\Users\seamonkey\Downloads\Aristois-Donor.jar
Then of course save the code and then run the file
