If it doesn't run on your machine, make sure to head to Java site, download and install the 32-bit JRE. This can be installed alongside a 64-bit JRE with no issues, if you're using a 64-bit machine. A reboot may be necessary.
On Windows 7 Installed Java 8, installed SeaMonster. Run Seamonster.exe, get the hourglass for a few seconds then nothing. So basically it does not run.
Seamonster works good.
