[Qgis-user] Unable to load project

Fri Jun 8 06:25:53 PDT 2018

Hi,

Years that I'm using the osgeo4w installer (advanced install) with three
concurrent releases  minimum (ltr, current release, dev, and sometimes
ltr-dev) and I can't recall on any issue I got due to this situation.
And afaics there's nothing to be particularly careful of, it's just about
click click click process and all got installed in the c:\osgeo4w64 folder.

Just wanted to share my experience.

Regards,
Harrissou
