I have successfully installed R (version 2.8.1) and RMySQL (version 0.7-4)

receive the following error-message:
Error in utils::readRegistry("SOFTWARE\\MySQL AB", hive = "HLM", maxdepth =
2) :
Registry-Schl?ssel 'S' nicht gefunden
Error : .onLoad in 'loadNamespace' f?r 'RMySQL' fehlgeschlagen

Does anyone have a clue what I should do? I don`t have any experience in
such issues. I have not installed MySQL on my PC. Could this be the solution
to my problem? Is it true that RMySQL does work properly on R only if you
first install MySQL?
That's what it looks like. I'm not sure why it is reporting 'S' as a
problem, but when I execute that line I see
> readRegistry("SOFTWARE\\MySQL AB", hive = "HLM", maxdepth = 2)
$`MySQL Server 5.0`
$`MySQL Server 5.0`$Location
[1] "F:\\Program Files\\MySQL\\MySQL Server 5.0\\"
$`MySQL Server 5.0`$Version
[1] "5.0.22"
and when I change the key to a nonexistent one I see
> readRegistry("SOFTWARE\\foobar", hive = "HLM", maxdepth = 2)
Error in readRegistry("SOFTWARE\\foobar", hive = "HLM", maxdepth = 2) :
Registry key 'S' not found
I'll take a look at readRegistry and try to improve the error message.
