crssync.exe - System Error

Describe the bug

After using OSGeo4W to upgrade my 3.12 install to 3.14

How to Reproduce
Use OSGeo4W to upgrade using Advanced and default selections.

QGIS and OS versions
Broken 3.14
Additional context

Website indicates that 3.14 is still in packaging and not released, so I guess what is occurring is OSGeo4W is applying a partial update and breaking the install.

@Saijin-Naib I think the issue is due to the protobuf library missing among the qgis package dependencies:

@ qgis

The same problem occurs with the standalone installer for 3.14 available at https://qgis.org/downloads/?C=M;O=D

If you manually install the protobuf library package using the OSGeo4W setup, then QGIS starts without problem.

I've filed a bug report on osgeo4w issue tracker: https://trac.osgeo.org/osgeo4w/ticket/634

@Saijin-Naib the bug was instantly fixed by @jef-n . The protobuf library was added as dependency of the qgis-common package.

#634: Protobuf dependency missing for QGIS 3.14 (both network and standalone
installer): installation aborts or QGIS doesn't start

Changes (by jef):

• status: new => closed
• resolution: => fixed

It is now possible to correctly install QGIS 3.14 via the OSGeo4W network installer.

The standalone installer was removed from the download server, waiting for a new fixed version to be uploaded.

Thanks so much to you both!

This issue is still happening. Is there a clean way to solve? I had problems trying to add SAGA, so I uninstalled everything and try to reinstall.

EDIT:
NOTE FOR EXISTING USERS: OSGeo4W v2 (previously known as testing) is now the regular repository. The latest QGIS release is only available here, as it already requires dependencies not available in the old repository. The long term release is additionally also available in the old repository using the same dependencies as before (see below). This also includes a 32-bit version, which OSGeo4W v2 does not support.
CAUTION: Upgrades of old setups using the new repository are not supported. You need to do a fresh install or use a different directory.
CAUTION: Windows 7 no longer works as we are now using Python 3.9, which dropped support for it.
