[Qgis-user] installing 1.7 standalone Win XP: Couldn't load PyQGIS., Python support will be disabled.

[Janneke Qgis]

Hi Milo,

I've tried the osgeo4w installer on Vista, which works. So I can give 
that a try on XP as well. However, I need to be able to work with the 
standalone installer, as our internet connection here (Tanzania) is very 
unreliable and rather slow, and a lot of our clients don't have an 
internet connection.

But you got me thinking about why it would be overruled by an older 
version: I'd uninstalled 1.6, but still had a version 1.5 installed. 
After uninstalling 1.5 as well there is no problem. I've now also 
re-installed 1.6 (standalone installer) and that now seems to work 
without problems (at least I can start up without error messages...).

Thanks for your help!
Janneke
