解决wine安装dotnet2.0的问题

使用winetricks安装dotnet2.0时出现错误：

    ------------------------------------------------------
    Instaling .net 2.0 runtime.  Can take several minutes.  See http://wiki.winehq.org/MicrosoftDotNet for tips.

    ------------------------------------------------------
    Note: command 'wine reg delete HKLM\Software\Microsoft\.NETFramework\policy
    2.0 /f' returned status 1.  Aborting.

在网上查了一下，基本上没有中文解答，好在发现了这个帖子，原来好多人也一样的遇到了这个问题，大部分人都是无解状态，好在7#出现了个lusida大侠给出了解释“The error was because winetricks never bother to check existence of two keys it tries to delete.“（出现这个错误是因为winetricks没有检查将要删除的键值是否存在。）

解决方法是添加那两个winetricks需要删除的键值让其删除：

    wine reg add "HKLM\Software\Microsoft\.NETFramework\policy\v2.0"
    wine reg add "HKLM\Software\Microsoft\.NETFramework" /v InstallRoot

PS：还可以尝试下载这个版本的dotnet来安装，winetricks已经于几周前在SVN中修复了这个小错误
