installation problems

hello, i have tried to install the file that i have downloaded from with this command
/bin/sh ./
but this is the answer
/bin/sh: 0: Can’t open ./

can somebody help me? tyvm

You have to change to the directory where the downloaded file is first.
Something like:
cd ~/Downloads
/bin/sh ./

yea having the same problem I’ll try it that way.
It did seem to work but where is the working icon??? Oh well it opened it in terminal all lines of code. What am I doing wrong???
Thanks in advance.
