Endnote X 3 updates

I have many computer problems and had to have my laptop reimaged.  So I just reloaded EndNote X 3 onto my laptop and noted that there are many updates prior to X4.  Are these updates downloadable to X3 without going to X4?  I haven’t the funds to upgrade to X4 yet since I’m on a pretty tight budget that has been frozen by operational Excellence.

You should run what ever upgrades are available to you, which you can do thru the help menu options of X3.  it won’t try to run X4 or X4 upgrades.
