I've just had this problem too, with a properly installed x64 JRE 8u45. Don't know if the Windows exe installer expects an x86 jvm?
Anyway, download the binary package
zip instead from Tigris (dead) GitHub Releases and unzip somewhere. It runs fine from there * with argouml.bat
, you just don't get a start menu entry added.
- EDIT: Your PATH must be correct to find the java.exe, easy way to check is to open a new Cmd shell (Start > Run... > cmd) and type
java -version
you should get something back from the jvm
