Writing to HKLM

[NewsArchive]

I'm trying to figure out why one of my installs will not write to
HKLM\Software\Intelligent Silicon\MyApp.

I'm running the installation from the windows Administrator account and its
Execution Level has been compiled as requireAdministrator yet I cant see the
registry entries in Regedit or Regedt32.

What circumstances could prevent SB from writing them?

I've knocked together this example app and I keep getting Failed on both Win
7 and XP.

Any ideas what I'm doing wrong?

Cheers
Richard
