Path warning during installation: "exceed the maximum length possible for a varible"

Hello, I’m trying to install the CUDA Tookit in windows 8.1 to use with Anaconda, but I’ve got this warning:

" The NVIDIA installer needs to add a path to the %PATH% environment variable; however, doing so would exceed
the maximum length possible for this variable. After the installation has been completed, please shorten the
%PATH% environment variable. And then prepend below mentioned paths to the %PATH% environment variable after the installation, or else try the installation again.

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\libnvvp;
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\lv10.1\bin;

"

So, what does it means? what I have to do? I tried the installation again and got the same message.
If the path exceed the maximum length possible for a varible, why NVIDA use that path?

Thank you for the help.

You need to learn about what the PATH environment variable is on windows.

Do a google search on that to learn about it and learn about how to modify it.

Then modify it to make it shorter. Remove unneeded things from the PATH variable.

Then rerun the installation.

Same problem here.Can you please say what should I do now? I don’t understand how to do so. Please
