TeraCopy 3.10 and 3.12 require AVX2 compatible processors for certain checksums

After a lot of head scratching and frustration we have discovered that TeraCopy 3.10+ will crash with certain checksum methods when the CPU in the computer does not support AVX2 instruction set. There is no warning or error messages. The application will just bomb out.

TeraCopy does not respond when clicking copy

Just started using Teracopy. It works great on one of my Windows 10 home.  

The other is running Windows 10 Enterprise edition. On this system TeraCopy does not work. It installs and seems 'ok' but after

selecting a source and target and clicking copy, nothing happens. You click and there is no response at all.

I've tried running the install in admin mode, starting in combability mode, etc. Installed with admin privilege's. 

Booting into Safe mode it didn't fix it either. 

Checked windows event logs and no signs of trouble.

Oddly enough using Windows File Explorer to copy files the Shell Integration of Teracopy works there for a copy. 

Does it just not work with Windows 10 Enterprise edition?

We will add AVX2 detection and fallback to SSE2 in the next version.

Could you please run this app to see if the detection is working?

I was having issues with TeraCopy and thought this might be the solution. Both the diagnostic file and the patch file trigger Windows Defender as malware. 'cputest' comes back as "Wacapew.B!ml" and teracopy.exe reports as "Wacatac.B!ml" which is rather serious malware. I would love an explanation for this as neither of these infections are typical of false positives.

This version is working on my old Xeon systems with all flavors of the xxHash.

Any thoughts on when the final fix will be posted?

Same issue for me. I set my Source and my Target, and clicking Copy does nothing.


Running Windows 10 Pro on a dual Xeon L5640 system. I'm a first-time user. I have large copy jobs and was evaluating the software.

I've uninstalled and reinstalled multiple times, but no change. I also uninstalled and installed version 2.3 (that worked), but version 3.12 is DOA on my system.

I've the same issue as well after purchase.
