Nvidia Driver in High Sierra

Do you mean an message "Some error happen ..."?
Thats because SIP disabled - but doesnt matter. And this is new in the installer since HS - before the installer doesnt check SIP enabled (safe, default) or not. If HS installer detect SIP diabled this "error" message pops up - forget it.
Let the installer make his work after the message.Do not abort the install.
All drivers are installed to /L/E and not /S/L/E anymore like Sierra and before!!!

And to use Web driver you must have nvdrv NVRAM variable set (normally done with Clover setting webdriver true)

Geforce 210 does not need the web driver.
Only check one "inject NVidia".

Do yourself a favor:
Do not open another thread with the same question/problem.

If you have new information or another question to the same issue, just use the "Edit"-function, which appears at the lower-right corner of your latest post.

In regards to your question:
Just download the driver with the Update-Tool, but install it manually, since there is an already known popup message, which blocks the automatic install with the Update-Tool.
If you install the driver manually, you will see the popup message, use the "ok"-button and finish the installation.

If all the necessary settings are done, like
- using a correct SMBIOS,
- using additional kexts (NvidiaGraphicsFixup),
- activate the "NvidiaWeb" in Clover, etc.
you should be able to reboot with working nvidia drivers.
