如何从崩溃的vivado安装中恢复或如何卸载部分安装

嗨，
当我在Linux系统上安装Vivado 2017.2时，由于与Vivado安装无关的原因，系统在安装过程中崩溃了。
这给我留下了一个带有“半安装”vivado的系统，一些文件到位，但很多都丢失了。
UG973中描述的卸载过程不起作用，因为没有
/.xinstall/Vivado_2017.2/xsetup
这可以用'-Uninstall'开头。
所以我用'rm -rf'删除了
/.xinstall/Vivado_2017.2
/Vivado/2017.2
并试图再次安装。
但是安装程序不允许我使用之前的版本，并假装仍然安装了2017.2。
必须有其他地方崩溃的安装留下一些痕迹。
问题：在如此崩溃的安装后如何（手动）清理？
最诚挚的问候，沃尔特



以下为原文

Hi,

when I installed Vivado 2017.2 on a Linux system the system crashed in the middle of the installation process, due to reasons which had nothing to do with the Vivado installation.

That left me with a system with a 'half-installed' vivado, some files in place, but many missing.

The uninstall procedure described in UG973 didn't work, because there was no

  /.xinstall/Vivado_2017.2/xsetup

which could be started with '–Uninstall'.

So I removed with 'rm -rf'

  /.xinstall/Vivado_2017.2
  /Vivado/2017.2

and tried to install again.

However the installer does not allow me to use the previous and pretends that there is still a 2017.2 installation. There must be other places where the crashed installation left some traces.

Question: How to (manually) cleanup after such a crashed installation ?

    With best regards,   Walter
