The installer gives the error “Internal error: Failed to get path of 64-bit Program Files directory.” on 64-bit Windows, how can that be solved?

This answer is for experts only. Click on Start, then click on Run and type regedit and press enter. Then navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ Then make sure the registry value ProgramFilesDir points to the 64-bit Program Files path, which is usually C:\Program Files\. Also make sure the registry value CommonFilesDir points to the 64-bit Common Program Files path, which is usually C:\Program Files\Common Files\.
