--- Comment #30 from Dorian Grey dorian.grey@mail.com 2010-05-06 03:59:03 --- I originally posted Bug 22547 (a bug with the same error message), got a duplicate and a reference to this bug:
Thus I tried the patch from Comment #28 with Wine 1.1.43. But unfortunatly it did not work (I got the same error message as before).
For testing I used the Open R-Community Tools (http://rcommunity.nazgulworld.com/index.php?page=dl) which also have the source code available (see also Bug 22547). They use the .NET Framework 2.0.
This might be easier than some closed source MS product.
