In the terminal, I navigated to the folder where the contents of the zip file were unzipped, labelled 'Stealth-Qt-1.2.0.1-Linux$' - I typed:
./Stealth\ Qt
Terminal returned:
./Stealth Qt: error while loading shared libraries: libqrencode.so.3: cannot open shared object file: No such file or directory
'libqrencode.so.3' is definitely in the folder.
Thank you for the output. The dynamic linker should look in the same folder. We'll double check that this is working correctly.
