program I wrote with a manifest to give it elevated privileges, so I can write
to the HKLM registry when requested by any of my applications. I use a
shared memory component (memory mapped file with no file) to communicate
between an app and the small program which is loaded when required.</span><o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span
lang=EN-US style='color:#1F497D'>But since Vista SP1 or SP2, Microsoft appears
to be preventing shared memory access between an app with standard privileges

reporting odd problems and this appears to be it.</span><o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span
lang=EN-US style='color:#1F497D'>So it appears I need an alternative
method. I could use the elevated DLL method, but this seems
complicated. I’m not an advanced programmer. It’s a bugger as I
spent quite a bit of time getting this working well when Vista first came out.
I would prefer to continue using the small app, but it appears I need some
other method for sharing text between 2 processes of different
elevations. Does anyone know if this is possible?</span><o:p></o:p></p>
