Since the things that went wrong below are due to spaces in directory names,
that probably does no harm to installing from DVD - there should rarely be
spaces in its mount point in Windows.

At least on the system in question, I could discover two jobs continuously
monitoring the file system for new files:
1. Windows Search (indexing service)
2. backup cron job
and on most system there probably is also
3. virus scanner
That said, what the installer is doing here is "uncommon": Files installed
normally do not get accessed immediately after. - This *might* be the reason
(one of the reasons?) here.

While I am in favour of asking the user to disable (3) during installation
(this request seems to be quite common, especially for installations not
using the system build-in installer), there will still be (1), (2).
Nonetheless, these will most likely exclude known locations for temporary
files (as %TEMP%).
