用vs2010windows installer生成的安装包,之前安装过老版本,卸载后安装新的版本,结果报错:“The following applications are using files which the installer must update. You can either close the applications and click "Try Again", or click "Continue" so that the installer continues the installation, and replaces these files when your system restarts.”
为什么出现这种问题,怎么解决?
