I unpacked into /tmp just to see if the program worked. I installed the key that I received in email and updated VPS. Then, the program doesn't run.
ehidle@Beluga:/tmp/avast4workstation-1.3.0/bin$ sudo ./avast
./avast: 178: /tmp/avast4workstation-1.3.0/lib/avast4workstation/bin/avast: not found
Any suggestions?
