If the self extracing NORSAR Software Suite installer hangs on Linux (never finishes unpacking), you can extract the tar.gz file for manual extraction. To get a tar.gz file type:

tail -n +165 NORSAR_Software_Suite_<version>_Installer.sh > NORSAR_Software_Suite_Installer.tar.gz

Then extract the tar.gz file with:

tar zxvf NORSAR_Software_Suite_Installer.tar.gz

Note: This will extract the files in the current directory.
