ReadRegStr with messagebox — NSIS Forum Archive

I want to make a ReadRegStr for my uninstaller, but cant figure out how I should do it. Have been looking arund in forum, but are not sure.

I want to find out if user has a speciel RegString in a known location. Lets say:

HKLM SOFTWARE\MyProgram "language" "english"

- If he has that speciel string, then I want a messagebox that asks what to do: Delete the string or keep the string. How can that be done?
