[osgeo4w-dev] Installer Change

[Matt Wilkie]

I've seen something which might be related: I installed to an alternate 
location (D:\o4w) and setup log files were still written to 
C:\OSGeo4W\var\log (setup.log, setup.log.full).

I don't recall any missing packages or dependencies, though I can't be 
sure about that and I've not done any further testing to try and 
reproduce it.

I am fairly certain I've never left setup.exe running while removing the 
C:\OSGeo4w tree. I have on occasion seen a program close their user 
interface yet still have a process shown running in Task Manager (most 
often with Firefox).
