[Wine] Wine fails to install/uninstall windows apps

[enrico.dini.verdiani@gmai]

I have Ubuntu lucid and trying to install Paint Shop Pro 8 on my system. I do
Applications>Wine>Wine configuration>Add application (psp8 ev in my case). I
choose Windows XP as Windows version and [ok]. Nothing happens.
So I go to the user/.wine dir and I try to install psp by clicking it from
there.
An installer appairs and asks me to remove/repair/modify my previous attempt to
install that damned software. First I try repair, but Wine stops me warning
about a failure in msiexec.exe.
My wine version is 1.2
Thanks in advance
