[Wine] Sibelius 6 does not work -user32.dll is not allowed to write

[MaSter_MiND_]

Hello
I'm using Wine 1.3.15 under Ubuntu 11.04 (just installed it, before I had Wine 1.2.2).
Sibeliuss 6 is not working for me (well I have VMWare + Windows 7, but this makes Sibelius 6 very slow, so it's hardly usable).
When I start it I get the Error:
"Error: 150021 (ERR_AUTH_REGTOOL_CANT_ACCESS_PIPE)"
When I klick on "OK" I get the next Error:
"Es gibt ein Problem mit den Datei-Zugriffsrechten. Sind Sie als Administrator angemeldet?" (Well I am German, and my English skils are not that well, but here's my translation of the error: "There is a problem with the file-access-rights. Are you logged in as administrator?")
I used IDA Pro so I found out, when I start Sibelius.exe, it starts RegTool.exe, which uses user32.dll, which wants to write to some adress, but it is not allowed to, so it crashes. So I am not able to start Sibelius 6. Is there a way to get this fixed, except for waiting for a release where this bug is fixed? (I read that I should not use wine in combination with sudo).
Hope someone can help.
