I have the beta version of Windows XP 64 bit that shipped just before the
final release installed at my 64 bit computer (Intel)
I have no recieved Visual Studio 2005 beta 2.

On the Windows 64 bit I have no special installation, no wierd configuration
and no virusscanner installed, but the .NET framework 2.0 refuses to
install, both through the VS 2005 beta 2 and through the framework
downloaded from the Microsoft web site.

I error I get is always something related that I have windows running in
safe mode or that the Windows installer is somehow corrupted. I tried
everything, downloading installer, downloading .NET framwork, critical and
custom updates... but the persist.

Installing it as 32 bit on Windows XP Pro no problem.

I have a dual boot, 32 and 64 bit windows. (Also linux)
The 64 bit windows works great, no known problem.

One report I found on the .NET framwork 1.1 was some bug that got into
conflict with the Data Execution Prevention. So this evening I am going to
disable try this, if it is possible.

Has someone out there an idea why this happens?
MSDN does not give a solution at this moment.

The goal is to test and develop 64 bit programs, in order to decide if that
is the direction to take.
But if the test fail, the why should we upgrade to VS 2005?
