Install to Raspberry PI 4

Hello, I am having trouble with Open CPN and want to switch back to qtVlm. I ony have qtVlm on my laptop. I am not sure how to install it on my RPI 4. I have downloaded two files just in case. the 64 bit and the 32 bit. One the website the first one and the last one. I extracted them to their own folder on the desktop. I have read the install file but it does not give enough information. I am not sure which one I need or even to install it, or does it just have to be opened? Not a total newbie but a little help would be appreciated.

Thank you in advance for any help, Dan

Hello, we have a moderation check on your first posts that's why it didn't came up right after you send it.

I also saw you get some primary answers on FB.

You confirmed that you had a rpi4 running a 32b raspbian. You can get qtVlm suited for this here: meltemus.com/index.php/en/download/category/9-raspberrypi you should take qtVlm-5.10-18-32b-bullseye

Uncompress directly in your home, and then first thing to check is the capacity to launch it from a console/bash (I assume you have basic knowledge of this => tell me if you need more details):
- launch a console
- move to qtVlm folder

A this point, note that we provide two versions:
- qtVlm => standard desktop version with a menu at the top
- qtVlm_touchscreen => uses the same look as the mobile version to be used with a monitor with touchscreen capacity

just launch one of these depending on your need

If all this is ok, will move to the next step

I have bullseye 32 is that raspian?
I downloaded the second one of the three.
I downloaded it and extracted it to Home/pi/qtVlm
I also have it in downloads as uncompressed.
I can gt it to show the icon now but the hourglass just goes around then stops nothing opens

I am in terminal
pi@raspberrypi:~ $ cd qtVlm
pi@raspberrypi:~/qtVlm $

pi@raspberrypi:~ $ cd qtVlm
pi@raspberrypi:~/qtVlm $ tar zxvf qtVlm-5.10.7-rpi.tar.gz
tar (child): qtVlm-5.10.7-rpi.tar.gz: Cannot open: No such file or directory
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error is not recoverable: exiting now
pi@raspberrypi:~/qtVlm $ ^C
pi@raspberrypi:~/qtVlm $

From the beginning:
- using a file browser remove the qtVlm folder you have in your home (/home/pi/)
- download: meltemus.com/index.php/en/download?task=...d&id=528&catid=9&m=0
- this will download qtVlm-5.10.18-rpi32Bullseye.tar.gz that can end in Download folder or elsewhere depending on your setting
- using a file browser move it to the home
- from a terminal, when you are at pi@raspberrypi:~ $ issue: - then: - from there:
