I need help with something-Please Help!

Ill take a look.
Why do you check for the usertype and the RapidSVN-Portable?
I would just overwrite it and save it to a file on exit.

EDIT

Here is it:

	RegistryBackup:
		;=== Check for registry permissions
		${registry::KeyExists} "HKCU\Software\RapidSVN" $R0
		StrCmp $R0 "-1" LaunchNow
		${registry::MoveKey} "HKCU\Software\RapidSVN" 
"HKCU\Software\RapidSVN-Portable" $R0
	
	LaunchNow:	
		${registry::RestoreKey} "$SETTINGSDIRECTORY\rapid.reg" $R0
		Sleep 100
		ExecWait $EXECSTRING
		${registry::SaveKey} "HKEY_CURRENT_USER\Software\RapidSVN" 
"$SETTINGSDIRECTORY\rapid.reg" $R0
		Sleep 100
		${registry::KeyExists} "HKCU\Software\RapidSVN-Portable" $R0
		StrCmp $R0 "-1" StopSplash
		${registry::MoveKey} "HKCU\Software\RapidSVN-Portable" 
"HKCU\Software\RapidSVN" $R0
		Sleep 100
		
	StopSplash:
		RMDir /r "$TEMP\${NAME}"
		newadvsplash::stop
		${registry::Unload}

You will have to remove the 3 line wraps I had to put in so it doesnt widen the page.
Thats the only part of your nsi file I changed. You have to create a $SETTINGSDIRECTORY variable pointing to /Data/settings or (if you want the option)to the settingsdirectory specified in the ini file.
And one question:
Why do you copy the whole stuff to the temp folder?
