How to solve the problem of "PATH environment variable size has exceeded its limit."

[Feng__Zemin]

Dear all

When I install C++ on my computer, there are the problem of path variables"  

PATH environment variable size has exceeded its limit.
Installation cannot continue because the length of your path is too long. 
 Suggestion: Exit the installation, eliminate unnecessary items in the PATH environment variable (you need to free more than 798 symbols) using Control Panel > System and Security > System > Advanced system settings > Advanced > Environment Variables and launch the installation again.

Could you tell me how can i solve it?

Thank you very much.

Check for (and eliminate) duplicate entries in environment variables:

INTEL_LICENSE_FILE=C:\Program Files (x86)\Common Files\\Intel\Licenses;C:\Progra
m Files (x86)\Common Files\Intel\Licenses

The above in an an example of the Licenses folder listed twice.

Remove old items no longer used:

INSPECTOR_2017_DIR=C:\Program Files (x86)\IntelSWTools\Inspector 2017\
INSPECTOR_XE_2013_DIR=C:\Program Files (x86)\Intel\Inspector XE 2013\
INSPECTOR_XE_2015_DIR=C:\Program Files (x86)\Intel\Inspector XE 2015\

For the above 2013 and 2015 versions no longer installed (I haven't cleaned this up yet). Use:

    Start | System | Change Settings | Advanced | Environment Variables

(the above is for Window 7, Windows 10 may have a slightly different route to reach the Environment Variables property page.
