B4R Question Project folder not set. You should first save the project. How to overcome this obstacle???

[krokiz]

Hi, all
Why is there such an error message? How does it help the user to solve the problem they stumbled on?
I installed B4R on my PC, and configured Paths. Started B4R and there was a template file(project). I selected my board (Nano 328P), serial port (the board is connected to the PC, apparently).
I click on Run(F5) and a window appears, saying:
Project folder not set.
You should first save the project.

I go to File -> Save (or press Ctrl+S) and nothing happens: I presume everything is fine.
I click on Run(F5) and the same window appears, again.
So I search on Project Tab, and there is no such an option, like 'Select project folder'. As I could not find it anywhere else into the IDE. ??? So, how to go on from here ???
I understand B4R is still v 1.0, but ... maybe it is just my bad luck to not be able to compile/run/test/save my(your) first project.

Are you sure that you've saved the project? Once you save it then it should work.

Do you see the project name in the top left corner?

I went on File and clicked on Save. The IDE does not complain and I presume It had saved the file. Also I press Ctrl+S, the IDE does not ask me for a project folder and/or file name(s).
There is no project name in the top left corner. there is only B4R, nothing else.
What am I missing?
I use B4A IDE for maybe 2 years and there is no such a problem right at the start.

You should have seen the "save as" dialog. Sounds like this issue: https://www.b4x.com/android/forum/threads/could-not-save-a-new-project.56587/#post-356228

Can you check it again with B4A and a new project? Do you see the dialog?

As a workaround you can download the attached project and double click on it to start the IDE.

I can understand that is a .NET bug/issue. I downloaded/extracted/opened the suggested project and started it from File Explorer: there is a project name up-left corner.
Anyway, I started the project (F5) ad here is the result:
B4R version: 1.00

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

I will explore the troubleshooting section and will come back to forum if I could not manage to solve the (next) problem I have.
Thanks for your time time spent on my questions. I really want to try and use your Arduino RAD tool B4R!

1. Make sure that this is the correct com port.
2. Make sure that it is not already used by another program such as Arduino IDE.
3. Disconnect and connect the cable again.
