[osgeo4w-dev] Significant Problems installing QGIS

Hi Jeff,

I'm not sure what to suggest next, it works for me.

I just removed all traces I could find of osgeo4w from my machine, 
namly: deleted c:\osgeo4w, removed startmenu entries, searched 
registries for occurences of "osgeo4w" and deleted those branches 
(excepting two Qt entries which I'm not sure about). Then ran 
osgeo4w-setup.exe (dated 30/12/2010 12:30 PM and 377,856 bytes), 
selected Express Install and just the QGIS and GDAL packages; defaults 
for all other choices. Start Menu items were created and qgis fires up 
without error.

My computer is Win7-pro x64.

My best guess for what is happening to you is a permissions issue. Is 
the username you login as a member of the local administrators group? 
(Start>Run: "compmgmt.msc" > Local users and groups > groups > 

You could try the commandline apt.py installer with python and see if 
that works for you, or at least displays some error messages which would 
help narrow down the problem:

1. If you don't have python already, download and install PortablePython 
2.6 (http://www.portablepython.com/wiki/PortablePython1.1Py2.6.1)

2. Get the current version of apt.py* 
    * pkg-apt Overview: http://trac.osgeo.org/osgeo4w/wiki/pkg-apt

3. Open a command prompt and set environment to use above (put attached 
portapy.bat in same directory as PythonShell-Portable.exe), remove .txt 
extension to use).

4. Run portapy.bat and from that shell the following commands:
set osgeo4w_root=c:\osgeo4w
python apt.py setup
python apt.py install qgis gdal

Tip: To avoid downloading the package archives again: after running "apt 
setup" edit or create c:\osgeo4w\etc\setup\last-cache and put the path 
to where the downloads are, minus the http* section, e.g.:


instead of "C:\osgeo4w-setup\http%3a%2f%2fdownload.osgeo.org%2fosgeo4w"

5. From this point open a new command prompt and run 
"c:\osgeo4w\bin\qgis.bat" *should* work (or 2x click in Windows Explorer).
