<br>
Hi Tom,<br>
the installation guide says:<br>
<br>
***<br>
Download OSGeo4W Installer and run it.<br>
<br>
Choose Express Install and select QGIS to install the latest release <br>
and/or QGIS LTR to install the long term release.<br>
<br>
Alternatively, instead of doing the Express install, you can use the <br>
Advanced Install, navigate to the Desktop section and pick one or more <br>
of the following packages:<br>
....<br>
***<br>
<br>
It's up to you to decide which version of QGIS to install. It looks like <br>
you have decided to install all the available QGIS versions.<br>
<br>
> 2. There is a new folder Desktop\OSGeo4W that has only shortcuts (over 30)<br>

<br>
Not sure what do you mean with "safely".<br>
If the folder contains over 30 shortcuts, I guess you have installed <br>
every single package available through OSGeo4W. That is not recommanded <br>
and not needed.<br>
<br>
> 3. If I start 3.40.6,<br>

<br>
<br>
This is correct.<br>
<br>
From the "Download" web page:<br>
<br>
"The long-term builds currently provide 3.40.6 'Bratislava'. Long Term <br>
Release (LTR) builds are intended for those who value stability over <br>
having the latest features. If you are unsure which version is best for <br>
you, download the LTR."<br>
<br>
<br>
> i. When I set the CRS to WGS84 (EPSG:4978) and try to add a raster<br>

<br>
First of all, are you sure you actually need to use the Geocentric CRS <br>
EPSG:4978 WGS 84? Usually the Geographic CRS EPSG:4326 WGS 84 is used.<br>
<br>
Anyway, based on your other message, I guess the issue may be due to the <br>
fact that in your OSGeo4W installation, the PROJ library related <br>
packages are not up-to-date.<br>
<br>
Regards.<br>
<br>
Andrea<br>
