Writing HKCU entries - UAC?


I'm trying to make Evernote portable with NSIS. I wrote a small script for this purpose.

When Evernote is started it wants to create HKEY_CURRENT_USER\Software\Evernote (with it's settings stored there) but UAC kicks in and asks if the user wants to allow this program to make changes to the system. I don't know why this happens because the current logged in user should always be able to write to his own user registry path.

If I add RequestExecutionLevel user to the script, UAC isn't used but the script seems not be able to import the necessary regfile (Settings [Install].reg) because Evernote thinks it has never been started before (and the regfile contains all necessary entries for it's key).

What am I doing wrong?

The script (atm it contains some lines that I could delete (e.g. for the x64 / x86 stuff, Evernote is only a true 32 bit application):


!define SNAME "Evernote"


!include "LogicLib.nsh"
!include "Registry.nsh"
