There is a program in Windows i.e. DCOMCnfg.exe which controls various operation of the computer by blocking and unblocking permissions on certain files. This program can block certain files from public access leading towards runtime 91 error. So, you should change the permission inside this program to public. However; this method is not recommended for new bie users.
