Hi David,

> java.lang.UnsupportedClassVersionError: BIOP_LibInstaller :
> Unsupported major.minor version 52.0

That error means that Java 8 is required, but you are running an older
version of Java.

If you update to Java 8, that error should go away.

If you are using ImageJ 1.x, you can download a version bundled with Java 8
from here:
    https://imagej.nih.gov/ij/download.html

If you are using ImageJ2 (what the Fiji distribution of ImageJ is built
on), then you can download a fresh version of Fiji bundled with Java 8 from
here:
    https://fiji.sc/#download

Unfortunately, most ImageJ2 and Fiji web services are currently down for
emergency maintenance, as we deal with a failing hard drive. Hopefully we
will have it restored by/over the weekend.

Regards,
Curtis
