I want to edit a
apalike.bst to suit my bibliography style requirements.
The path of this file on my Windows OS is:
C:\Program Files (x86)\MiKTeX 2.7\bibtex\bst\apalike.bst
I made a copy of it, named
myapalike.bst. I used notepad to open it and made the required changes. Then, while saving it, it showed a warning "Access is denied". And the changes were not saved.
