QGIS 1.5/dev does not start anymore under XP + 64bit issues

[lutra]

Scenario:

newly installed XP 32bit sp3 machine, no other programs installed.

Downloaded osgeo4w.exe

Installed qgis 1.5 -> when launching the program

"the application failed to initialize properly (0xc01500002)"

Tested also to install qgis-dev, the result is the same.

I also tested to install QGIS with the standalone installer (that by the way is derivate from osgeo4w) and the message still the same.

On a freshly Windows Seven 32 bit installed machine no problems, QGIS starts fine, both with osgeo4w and standalone installer.

The very same message appears when trying to launch QGIS 1.5 installed with the standalone installer in a Windows XP 64 bit machine (again, just installed).

The message that shows under XP 64bit, when trying to launch qgis/osgeo4w is different, as it says that "proj_fw.dll" is missing. In this case (xp 64bit + osgeo4w) there is probably also another problem:

when it comes to choose what packages/libraries to install, the installer does not marks automatically the dependencies, so it makes very hard to make a correct installation.

I miss to test how it works under Windows Seven 64bit, test that I will do in the next hours.

PS

Yes, I have tested to install the "Microsoft Visual C++ 2008 Redistributable Package" for the proper architecture and doesn't change a thing.

I exclude also conflicts with other (GIS) software as all the machine had just installed OSes.

this problem does not appear when installing osgeo4w under Seven 64bit

it works fine, no problems at all, as under Seven 32 bit.

I'm puzzled about the situation under Windows XP. In all the machines I tested I'm experiencing the above problems (never seen before... and I've installed qgis hundred of times), while I've been told by another person that it seems to still install/work fine.

I believe/suggest more tests under XP.

I forgot:

under Seven 64bit/osgeo4w under QGIS 1.5 the GRASS plugin is not available, while under QGIS-dev it is.

Let's say that I cannot confirm this problem, so I'm closing the ticket.

Every XP virtual machine where I use to make tests with QGIS seems to suffer of the

"the application failed to initialize properly (0xc01500002)"

but under "real" PCs seems to work fine, so after all it maybe just a problem with the virtualization software (Virtualbox) and XP.
