Version 2.3.60 [driver version 2.3.60.206]

I compiled Callbackfilter Encrypt header sample with Win 32 [in vc++ express]

It is working fine in Win 7- 64 bit

But not working in Win 8.1 - 64 bit

Error: During set filter the error "System cannot find the file specified" is displayed. Check attached image.

I have not tried with 64 bit compilation.

Note:
Version 2.3.58., 2.3.59 were working in Win 8 64 bit when compiled with 32 bit in VC++ Encrypt header sample

Windows 8.1 has not been released yet. As Microsoft tends to break operations in new Windows versions all the time (the same happened with Windows 8 and with Windows 7 before), we need to update the code accordingly. CallbackFilter will support Windows 8.1 when the latter is released and we have a chance to test and update CallbackFilter for this version of Windows.


Sincerely yours

Do you use the old library file building Encrypt sample ? It could be a problem with a AddBytesToWriteBuffer CallbackFilter api, that is requires a cbflt3.lib (cbflt3.dll) from the same build as a driver binary.

Eugene Mayevski: Thank you .... lets wait for final release of win 8.1 .. will report back if required.

Vladimir Cherniga: cbflt3.lib may be for version 3 of callbackfilter. I am using version 2.3.60 [latest as on date] and it comes with cbflt.lib

Sorry confusing you, please check that you don't use cbflt.lib from the previous version.
