i have windows server 2019 with 2 x Xeon E5-2680v2
i try install opencl runtime 18.1, but i get an error "CL_PLATFORM_NOT_FOUND_KHR"

Maybe Xeon CPUs have a special OpenCL runtime? I don't know. But hashcat should work just fine if you have a correctly installed OpenCL runtime.

Also i have another machine with Windows Server 2012 and Intel Xeon Gold 6154, and it's have same troubles.
if anyone can start hashcat with Windows Server system and Xeon - tell me how.

Read the Intel version(s) Release Notes very carefully here:
https://software.intel.com/en-us/article...ase-notes/
Be mindful that Intel is not above leaving 'legacy' CPUs in The Purgatory of Deprecation!
Additionally search for "Intel OpenCL upgrade problems"- some have had glitches when
upgrading from 16.0,01, and 02 to 18.1. Remedies may include deleting a couple registry
keys and routing-out remnant dll files manually. Good Luck!

I don't know how, but i do it. I reboot the server in 2 times and reinstall opencl runtimes 18.1, and it's work. But machine have 2 processors, then hashcat see 3 processors. Device 3 named same other two, but get error. if i start hashcat with "-d 1,2" parameter - it's work and give 80 h/s on -m 15700. Sorry for my english...
p.s. Xeon Gold 6154 give 84 h/s on Scrypt (-m 15700)

please post the output of:
hashcat -I

it's strange, but server have 2 same Xeon, and it's work only, if i start it with "-d 1,2", else i get error "CL_INVALID_PLATFORM".
Anyway two Xeons hashrate was enough for crack my Ethereum wallet hash with my password-candidate generate method, and it's cracked in 3 hours. I was try crack it with GTX1080 ti, and rigs with 8*AMD RX580 and rig with 14*GTX1070 before, GPU give maximum 1 hash per second from card.
Thank you for help.

From Intel's OpenCL Troubleshooting Notes, FWIW....
"OpenCL™ programs are said to observe an extra, non-existant CPU platform and/or device. Uninstallation of 16.1.2 may leave assets on disk... the following system alterations should help complete uninstallation procedure for 16.1.2:
1) Remove following registry keys:
On 64-bit OS:
HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors\intelopencl64.dll
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Khronos\OpenCL\Vendors\intelopencl32.dll
2) (optional) Remove following files if they exist:
On 64-bit
C:\Windows\System32\intelopencl64.dll
C:\Windows\SysWOW64\intelopencl32.dll
*End update 20181025*"
For more information on manual installation of runtimes, users should refer to the guidance in section 5.1 of the release notes.
