SweetHome3D-6.0-portable How to start from USB-stick

[otadmin]

I am on linux-mint 19 and am using sweethome 3d since a while. Just downloaded SweetHome3D-6.0-portable and unpacked in on a USB-stick to take my projects to other computers.

Question is how to start the program from the stick? If I double-click SweetHome3D-linux-x64 a text editor opens showing the code but does not run sh3d.

Don't open [font=courier new]SweetHome3D-linux-x64[/font] with a text editor but run it as a script using this tip or in a Terminal window.
Depending on how you copied files on your USB stick, you may also have to reset execution rights on [font=courier new]SweetHome3D-linux-x64[/font] and [font=courier new]jre/linux/x64/jre8/bin/java[/font] files.

Thanks, clear to understand. Learned about permissions!

Now I get Error: Could not find or load main class com.eteks.sweethome3d.SweetHome3D . On the portable version the Furniture is in data.

This could mean that you moved some files in [font=courier new]lib[/font] subfolder.
As explained at the end of the README.TXT file, you shouldn't move files found in the uncompressed folder.

Just started up again. Nothing works! Whatever advice I implement the file opens in the text editor.
I formatted the USB-stick to fat32 to be able to run it on different OS. But under linux I am unable to change any permissions.
Noticed that the file name is SweetHome3D-linux-x64 with no ending. Should there not be a .js at the end?

Just to mention, it works fine when the stick is formatted to ext4. But then windows will not work with it.
