Problem to install last version

i have a problem to install the last version.
During installation, i have this message : "Musescore 2 Setup : Could not open key :
HKEY_CURRENT_USER\SOFTWARE\Classes\Applications\Musescore2.exe\SupportedTypes.
Verify that you have sufficient access to that key, or contact you support personnel".
Is it possible to explain me what i have to do to resolve this problem? A
older version is installed, it's the 2.0.2 version.
