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.
- ------------------------------------------------------
- prerequisite gecko already installed, skipping
- Setting Windows version to win2k

- ------------------------------------------------------
- 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
