Aftershot Pro X64 starts with an information dialog that there is a new version available, but after hitting on the given links nothing happens. Starting Aftershot from the command line shows up that there is some problem with the Mozilla XUL library and the Aftershot provided libstdc++.so.6 lib. Instead of using the system default library, it relies on the delivered version. This could be easily fixed by removing any read access right on the symbolic link target:
cd /opt/AfterShotPro2\(64-bit\)/lib chmod -r libstdc++.so.6*
Afterwards the links are working and refer to the download location for the new version.
