I am trying to run VIPER on a machine with Windows Vista. But viper-gt
does not run. The errors are listed below. Any help is appreciated!

Perl (and the required libraries) have marched on, while viper is
currently dormant (I really should shift its dev status on sf.net).
Anyway, you can get most of the functionality (less some scripts for
generating .gifs with a version of lib-gd that doesn't seem to exist
anymore) with the viper-light package, which doesn't require running
any installation scripts.

David:

I received the error mentioned when I ran viper-gt that is part of the
viper-light package. Prior to that, I tried installing the full
version with no success.

For the light version, all I did was unzip the file, and run java -jar
viper-gt.jar in the appropriate directory. That threw up the exception
errors. (As an aside, I have a pretty new version of java).

Thanks,
Naresh
