[Dx4win] My Vista experience

[Roger Marrotte]

Paul,

I'm running Windows Vista Home Premium.  I'm running as an administrator.
After seeing your email I installed DX4WIN and when asked if I wanted to run
it I said yes and it worked.  I then exited DX4WIN and tried to rerun it and
it wouldn't run.  I received the usual message about copying the file
vichw11.sys and the program exited.  I then reinstalled DX4WIN and when
asked if I wanted to run the program I said yes and it ran again.  I exited
DX4WIN and tried to run it again and it would not run.

We're getting close but no cigar.

Roger, W1EM

Hi,

I installed Virtual PC 2007 (free download from MicroSoft)
and installed Vista Ultimate under the virtual machine.
(for the time being I have no plans to install Vista on any of
my machines)

When running as administrator, DX4WIN runs fine. I do not get any
error messages etc and the port driver is loaded. As a regular user,
the port driver cannot be loaded. Versions prior to 7.03 would exit
when this happens; I modified the code for version 7.03 to ignore
this error, with the result that access to the LPT port(s) is disabled.

I guess that the experiment worked, because my laptop is 32 bits. If
you run the 64 bits version of Vista, loading the device driver will not
work; even for the administrator.

Will keep you posted,

--Paul
