FreeFileSync Forum

I've found and repaired the problem !

The function, which Windows is use to verify the signature, is a part from the 'WinTrust.dll'.
Thanks to autoitscript.com-forum for the info.
The registration of the dll was broken and I fixed him as follow:

- Open a commandline as admin
- Execute "C:\Windows ...

I'm not give up yet! But the Win10 notebook of my wife, is also a 1607 and there isn't a problem with SigCheck.exe. So the reason must be in my (pretty normal) installation.

Maybe a problem with the Windows "Certificate Root Store". But I didn't found a solution to check/repair it...

The latest Win10 is not distributed to my notebook via update. Maybe a hardware/driver incompatility.
I don't want to force the upgrade !

I'll search for a solution with the sign-check for 32bit (and live without FFS :-( )
Thanks for your help...

Also a deinstallation of AVG Antivirus, with a followed restart didn't help.
Setup shows the same error as before and sigcheck.exe (32bit) not work.

e.g.: On the second notebook from my wife, SigCheck.exe works.

D:\Neu\SigCheck>sigcheck.exe sigcheck.exe

I've downloaded the installer multiple and also from another location. All the same !

How can I check it ?
SigCheck from SysInternals ? Why is "FreeFileSync_XP.exe" used and not "x64" on Windows 10 x64 ?

I've used FFS Free until yesterday, when I updated from 9.1 to 9.5.
I received the following error:
FFS_1.jpg
A later start brings:
FFS_2.jpg

I've disabled the AVG Antivirus while the setup, but the error is the same.
Setup an old V9.4: Same problem.
And also my old setupfile V9.1, that works ...
