Has anyone used it? Any problems? I saw a followup message that said it
errors on Win ME but as the minimum spec for our software is 2000 I'm not
too bothered about that. I'm just interested that it doesn't affect win2000
and that it runs on xp with no problems.

Thanks.

I could be wrong but I don't think 2003 supports restore points either.
They ditched it for something else.

XP/2003 Pro also has system restore (e.g. x64 version) so it was *not*
ditched.

It is not present in the Server versions for whatever reason but it is in
Pro builds.

I think you could be right - I can't find the system restore icon on our
server anyway...
I can't believe they removed it! IMO it's the best thing Microsoft have
ever added to windows - it's saved me loads of times.

Really? IMHO was a pile of junk and I'm glad they got rid of it. The way
it monitored files based on a list of file extensions was just
completely stupid. Even that list itself was weirdly chosen, it for
example included GDB, the Interbase database file extension!

Ah I've never studied how it works and I have to admit I've found it
unpredictable with regards to what it restores and what it doesn't but the
undeniable fact is I've reinstalled XP about once a year on average while
all previous OS's have seen me reinstalling around once per month. Windows
doesn't last long around me :)

I might just not bother with system restore as I'm not sure i'm happy with
the reliance on vb script being installed and enabled. Plan b is to move an
msi i run after install to the beginning of setup as it creates a restore
point anyway

Here's the delphi code (so should adapt pretty well to inno, dunno) for a
pure, nonvbscript approach

http://www.swissdelphicenter.com/en/showcode.php?id=1650 (it lists both the
vbscript and dll approach)

You are correct in wondering if vbscript is reliable. It is preinstalled on
both these systems but removable. Furthermore many AV scriptblockers would
screw you up.

But..... since Systsm Restore points are available only on Windows XP and
ME, and have indeed been dropped on 2003 Server, the point is questionable.

BTW I suspect the reason why the code wasn't reliable on ME is because of
this note from MSDN

Windows Me: By design, SRSetRestorePoint fails if there are pending file
rename operations. Therefore, to avoid a failure, call SRSetRestorePoint
only after the computer has been rebooted. Pending file operations are
stored in the Wininit.ini file.

I translate this as saying Restore Points are pretty worthless in ME, as
that is a big inconvenience. Still I sure do like them in XP. Ah well.

Thanks I'm not great with Pascal but I'll give it a go!

Well, *technically* you're not supposed to be installing anything when
there are pending rename operations either (since the system might be in
a slightly funny state). Not that it seems to bother most people :)

Right but in this case it deliberately fails and its vague as to WHERE the
files are (system files, sure)

What does erstellt mean? babelfish reckons 'provides' but that doesn't make
much sense. I'm guessing created or successful?

And I see it uses vb script. Is that always available in XP?

'Erstellt' in this context means 'created'
