NSIS 向path增添应用程序安装路径
系统路径path的注册表项
!define PRODUCT_UNINST_ROOT_KEY "HKLM" //HKEY_LOCAL_MACHINE的简称
!define PATH_KEY "SYSTEM\CurrentControlSet\Control\Session Manager\Environment" //path对应的HKLM下的注册表项
在安装完成后字段区添加
Var vPath //新加,自定义变量,用于接受原path中的变量值

WriteUninstaller "$INSTDIR\uninst.exe"
WriteRegStr ${PRODUCT_UNINST_ROOT_KEY} "${PRODUCT_UNINST_KEY}" "DisplayName" "$(^Name)"
WriteRegStr ${PRODUCT_UNINST_ROOT_KEY} "${PRODUCT_UNINST_KEY}" "UninstallString" "$INSTDIR\uninst.exe"
WriteRegStr ${PRODUCT_UNINST_ROOT_KEY} "${PRODUCT_UNINST_KEY}" "DisplayVersion" "${PRODUCT_VERSION}"
WriteRegStr ${PRODUCT_UNINST_ROOT_KEY} "${PRODUCT_UNINST_KEY}" "URLInfoAbout" "${PRODUCT_WEB_SITE}"
WriteRegStr ${PRODUCT_UNINST_ROOT_KEY} "${PRODUCT_UNINST_KEY}" "Publisher" "${PRODUCT_PUBLISHER}"
ReadRegStr $vPath ${PRODUCT_UNINST_ROOT_KEY} "${PATH_KEY}" "Path" //取原值
strcpy $vPath "$vPath+$INSTDIR" //字符串连接喽
WriteRegStr ${PRODUCT_UNINST_ROOT_KEY} "${PATH_KEY}" "Path" "$vPath" //写新值
