The issue is that src/RegistryTool.cpp wants to write to HKLM to which normal users doesn't have access, and therefore perspective effect (and everything else that use registrytool) blows up.
Registy tool should probably use HKCU instead or HKLM and it should work even for normal users.
A manual workaround is to use regedit and go to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\inkscape.exe
and give full control permissions to Users
(right-click->Permissions->select Users, check Full control checkbox, Ok)
