Select my product from a list
tablet, ICONIA A, A1-810
One driver is shown. It installs on a Windows
computer, to talk to the tablet. (Making this a
WinXP question.)

From the download page for .NET 4.0 Framework, it looks
like WinXP SP3 is an included OS. Are you at SP3 ? You
might need to be patched to SP3, to install .NET 4.0. The
.NET 4.0 installer may run silently, and perhaps you
didn't notice a dialog on the screen for it.

You would want to get Aaron Stebner's .NET Verifier Tool and
verify that 4.0 is working OK. Look for netfx_setupverifier_new.
When you click it, it should start to download.

netfx_setupverifier_new.zip 239KB
Extract the netfx_setupverifier.exe file from inside
there. And then you can double-click to run it.
In the "Product to Verify" field, select
.NET Framework 4 Client. Then click "Verify Now".
If you have the Client installed, it will say
"Product verification succeeded!". The means your
FX40 went in OK.
There is only one other detail, and you aren't presenting
any symptoms for that (keywords: ngen executequeueditems).
That's a WinXP specific issue, but shows up at boot time.

The page here, seems to indicate the A1-810
is MTP (Media Transfer Protocol) over USB.
http://sourceforge.net/p/libmtp/bugs/856/
And that means, check that your Windows Media Player
is up to date. MTP is part of WMP (for reasons only
Microsoft understands). MTP is a file-level protocol,
transferring whole files, and honoring a raft of
DRM features ("Do Not Copy" and friends).
http://en.wikipedia.org/wiki/Media_Transfer_Protocol
"Versions of the Microsoft Windows operating system
from Windows XP SP2 support MTP.
Windows XP requires Windows Media Player 10 or higher"
That's the laundry list for now
You would need to look for a recently generated
.log file, to see if something else was failing.
You could also check Add/Remove programs and see
if there is an Acer entry now.
*******
One other thing.
USB devices are either to be plugged in during
software installation, or after software installation.
The installer may tell you what to do. I would not
plug in the Iconia myself, until all of fthis installer
nonsense is finished. Otherwise, it might just attempt
to use vanilla MTP and show up as a disk or something.
I don't really know what to expect, in terms of where
to look or what window should pop up, when the Iconia
is connected. If it was an MTP device, you'd think it
would look like a disk or something.
HTH,
Paul
