Hi JC and Mark--
I've used several Betas of Office 2007 and now RTM on several builds of
Vista (now RTM), and this is an interesting, strange problem that I've never
encountered personally. I have no idea if this is more wide spread.
I checked the MSKBs and did not find this issue. I did find one MSKB that
is not directly on point, but did mention a read only problem that has to do
with protected docs and an editing restriction, and I linked it below. I
know the errorYou may want to post this on the MSFT Word group or Office
general group, because a large concentration of specialized Office mavens
who consult for a living and are authors on Office and Word hang in there.
If you're using WinMail or a box with OE to read the groups, you can search
by key words using View>find.
You receive a “This modification is not allowed because the document is
locked†error message when you modify a document in Word 2007 or in Word
2003

The reason I comment is that many times Vista has been on one drive, and I
have installed Office 2007 on another drive with no problems. The only
problems I have seen with regard to Vista and Office 2007,and they were a
pain and required manual uninstalls were with Office 2007 and One Note
trials that did not want to completely uninstall and interfered with
installing the RTMs.
Good luck,
CH
