ntprime64.exe crashes

[mikeblas]

On Windows Server 2019, I'm trying to run ntprime64.exe version 30.8b15. It crashes without producing any output:


[code]
Faulting application name: ntprime64.exe, version: 0.0.0.0, time stamp: 0x6275744e

Oddly, I have the same code running on a different Server 2019 machine without any problem. What could be the cause?

No idea. Does prime95 run OK?

Sorry if I'm stating the obvious.

What are the permissions on the c:\prime99 folder ?

Did you try to run Prime95 as suggested ? The readme file says one has to "install" it in the same folder and run it. (George perhaps the p95v308b15.win64.service.zip file also should contain the Prime95.exe file. An space saving alternative would be for it to contain only the ntprime64.exe and the readme.service.txt files.)

Then the readme.service.txt contains instructions and recommendations.

Since it is the failing module you could try a more recent version of libhwloc-15.dll : https://www.open-mpi.org/software/hwloc/v2.7/. But don't try version 2.8 : I tried it and it gives the error you describe.

Same issue here, still on a Server 2019 fully patched machine: I've tried to update ntprime64 from a former version (30.8.something) to 30.8b15 by running (as multiple times before, even on different machines) in a terminal with elevated privileges

ntprime64 -remove
ntprime64 -install

and suddenly realized something was wrong since the install did not respond with the usual "NTPrimeService installed " (or something like that).

Trying to launch the service, both with elevated privileges and not, yields

NET START  NTPrimeService
The service is not responding to the control function.

and puts

Log Name:      Application

into the event viewer.

Prime95 runs fine, from that same folder.

So far I've tried updating libhwloc-15.dll to the version suggested by S485122 (2.7.2), same result. As suggested by a number of Msoft posts related to "Event ID: 1000" or "Exception code: 0xc0000005", I've also run

DISM.exe /Online /Cleanup-image /Restorehealth
sfc /scannow

again with elevated privileges, to check for corrupted items on this machine, and both commands return a clean situation. As a last resort, I've also eliminated all references to both "Prime95" and "NTPrimeService" from the registry, in order to attempt a new clean install... nope (afterwards restored from .reg files).

I'm running out of ideas... any Server 2019 pundit around, willing to help me sort this out?
TIA
