The installer doesn’t quote the uninstall string appropriately.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Notepad++\UninstallString is

C:\Program Files\Notepad++\uninstall.exe

when it should be

“C:\Program Files\Notepad++\uninstall.exe”

And similarly in wow64node for 32-bit version.
Can you please tweak the installer to quote this so that people don’t have to waste time “remediating” this?
