From your deleted answer to another question:
I am experiencing the same problem with Windows 7 Professional SP1. I am missing several projections, including EPSG:4326, while others are being listed in French.
I have tried both 32-bit and 64-bit installations, as follows:
QGIS-OSGeo4W-2.2.0-1-Setup-x86.exe and QGIS-OSGeo4W-2.2.0-1-Setup-x86_64.exe
The postinstall.log file for the 64-bit install shows the following, starting at line 93:
'"C:\PROGRA~1\QGIS"' is not recognized as an internal or external command, operable program or batch file.
OSGEO4W home is C:\PROGRA~1\QGIS Valmiera
Synchronizing CRS database with GDAL/PROJ definitions.

CRS update (inserted:0 updated:0 deleted:3631 errors:0)
No CRS updates were necessary.
The CRS synchronization breaks because of the blank after QGIS. The OSGEO4W home vaiable should not contain any blanks. For me, it reads C:\PROGRA~2\QGISDU~1\
