has there been any update on this issue?
I am having what seems to be a similar problem. Running the .sh as instructed provides:
Boxcryptor_Portable.sh: line 6: ./../runtime/bin/java: cannot execute binary file: Exec format error
Filesystem doesn't support native execution, starting fallback procedure
Boxcryptor_Portable.sh: line 32: /lib64/ld-linux-x86-64.so.2: cannot execute binary file: Exec format error
I am running this on a 64 bit system.
Thanks in advance for any help.
