I did some search here in discussions and I did not find anything related to my problem, so I'm posting this.
I'm using Win7 Professional 64-bits and I have Office Home and Student 2010 installed.
I followed the instructions for installing BibWord and the styles did not appear in the list here.
Later I also tried to copy the Bibliography\Styles folder into the 32-bit Program Files Folder, tried Common Files, AppData, and no one of them made Word show up those styles.
I'm not finding anything related on MS Office Support, Google also did not return any good alternatives, and I'm stuck at this for 3h already =/
Thanks for any help, sorry if I'm reposting something.
