Working simultaneously with one library

Assuming that two poeple want to work with the same library at the same time- may this cause problems to EndNote?

I tried it once but it didn’t work…

Hi,

where can I set the file properties so that there is only the “read- only” (or “write- only”) directory? Can I do it myself or does our  administrator (who installed the whole programme on our computers) have to do this as we possibly have not the same “rights” on this programme as he has?
