The latest version does not find passwords for MsOffice 2013 on AMD Radeon 7970!
Version 3.10 works correctly on the same computer.
The latest drivers for AMD 7970

I put screenshots and hashes...

Hashcat64.exe -m9600 -a 0 --remove office2013.hash office.dic


$office$*2013*100000*256*16*9C0D1C43575992F70F1BD063F3A2D294*4CE783C9873CB64FF92FDF77805E5DA5*84CC00D24C143EDFF2CEC57BFFA69A64FD49BC122143A25DFFEFBD832179E7D5

Please retry with latest beta from hashcat.net/beta it has a self-test functionality of the drivers/device used. If it doesn't complain on startup, your password is invalid.

I tried the beta version ...
Launched a benchmark for hashes of MS Office 2010 and MS Office 2013 documents.
For MS Office 2010 - is fine...
For MS Office 2013 - Attention! 
passwords for MS Office 2013 was not found in AMD RADEON HD 7970...
password for document is valid.
I created a test document with a known password and tested ...
I reinstall drivers and followed all recommendations hashcat.net/faq/wrongdriver

see atachments...

If the self-test failed it's a driver problem, otherwise it would fail for everyone. Vendors started to abandon their old products for use with OpenCL in latest drivers. Drop the 7970, buy some recent GPU.

But why version 3.10 on this driver finds the password successfully?!!
This problem is also on my laptop with AMD R5 M430...

In 3.10 there was no self-test implemented, therefore there's no such error message.

Yes hashcat v3.6.0 uses an improved kernel code which supports cracking passwords > length 16. Your OpenCL runtime fails to compile clean code for it and that's why you get the warning message "OpenCL kernel self-test failed". This is _not_ a hashcat problem. If you use a different OpenCL runtime, you will find it working. A different OpenCL runtime however requires different hardware, that's why I said you should drop the 7970.
