Comment 33 for bug 365881

Using Win XP Professional:
I had the problem first without an error message (on a laptop) - Wubi made the drive lamp blink for a minute or so and then went back to sleep. On the other machine wubi exe on the 9.04 disc and the downloaded installer both produced the insistent error message from pyrun, which itself was hard to get rid of.
I tried closing down all peripherals but to no avail: finally I tried the "desperate click" method described above and eventually I got the installer window. My Kaspersky asked several times if I would allow pyrun to communicate with home (wherever that may be) and I did; after that installation proceeded normally.
 Obviously a bug, and one that is not going to encourage new users to use either Wubi or Ubuntu. Let's hope someone can fix it!
