Intel folders in the PATH variable

Are all these intel folders required in the PATH variable after driver installation has been completed?

A recent software installation failed because it found the PATH variable was too big, so I want to remove anything that is not required.

If these are all required, is it ok to create a short symbolic link to these longer pathnames, and just use that short name in PATH?

Alternatively, could I relocate the contents of "Intel(R) Management Engine Components\DAL" and "Intel(R) Management Engine Components\IPT" to a single folder with a short name?  Will the intel software still work?

(using Intel Core i7-4770 with Win7 64 bit)

PATH contains:

C:\Program Files (x86)\Intel\iCLS Client\;

C:\Program Files\Intel\iCLS Client\;

C:\Program Files (x86)\Intel\OpenCL SDK\3.0\bin\x86;

C:\Program Files (x86)\Intel\OpenCL SDK\3.0\bin\x64;

C:\Program Files\Intel\Intel(R) Management Engine Components\DAL;

C:\Program Files\Intel\Intel(R) Management Engine Components\IPT;

C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;

C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\IPT;
