Cannot Compile (Delphi XE)

[Vinski]

Hello,

I just upgraded to Version 2 of DOCXReadWrite, but now the program won't compile.
I get an Error in the following line, which is part of the unit "AXWSynCrypto"

Code: Select all

{$ifdef USEAESNI} (cfAESNI in CpuFeatures) or {$endif}

Delphi says "Undeclared identifier cfAESNI"
and "Undeclared identifier CpuFeatures"

Did I mess up Installation?
If yes, how do I install correctly?
If no, what can I do to solve this problem?

Hello

I don't recognize that code line. Can you please show some more lines.

Code: Select all

unit AXWSynCrypto;

  nor memory usage inside the Thread handler

     for faster System.pas and FastMM4 (no locking)

Hello

I have posted a new update now. Please download it.

[Vinski]

Hello,

I installed the update, but it seems, that the Unit

Code: Select all

unit AXWSynCrypto;

has not been changed.
Hence the Problem persists and
"cfAESNI" as well as "CpuFeatures"
remain undefined.

I use Delphi XE.
