XE7 users, could someone please double check something for me please. Check the value of this registery entry HKEY_CURRENT_USER\Software\Embarcadero\BDS\15.0\ProductVersion
I have the value of 20 but I believe that it should be 21, as it meant to match the Product Version of http://docwiki.embarcadero.com/RADStudio/XE7/en/Compiler_Versions
