Tonfoto is getting stopped by Smart App Control in Windows

Elynde

Windows 11 build 26200.8737

Windows is saying it can’t confirm the publisher of this app and is blocking it from launching. Is there a work around?

Elynde Tonfotos files are signed with digital signature to confirm publisher. This signature has already gained trust among major antimalware vendors and was trusted by Microsoft from day one as we were making specific steps for that. It has been a while since we updated our digital signature and got reports about false alarms like this from users, and ususally those were coming from less popular security vendors.

So it is really strange to hear about that. Actually, Tonfots is running on tens of thousands of Windows 11 computers without issues. So this looks more like specific issue of your PC and your copy of Windows. AFAIK there is no way to add application to exceptions so the only thing I can think of is to contact Microsoft support for help. Or, you can disable Smart App Control permanently, but this is not something I would recommend doing.

Hi, same happens to me today..
Andrey
Win 11 Pro (25H2 26200.8875)

Tonfotos 1.16.0 (seems like small launcher app not signed)
C:\Users\<mysuser>\AppData\Local\tonfotos\tonfotos.exe (19th July 2026)
same folder Update.exe not signed….

if I go into C:\Users\<mysuser>\AppData\Local\tonfotos\app-1.16.0
there is an tonfotos.exe app which seems to be signed with cert thumb: aeb9e43381f6ae0d8e9bf6f53f91f78212bd9150

But my shotcut on desktop points to “the launcher”….

I can launch app from subfolder app-1.16.0 with no issues. Can update.exe and “launcher” app be signed as well or should I update my shortcut to subfolder? Will autoupdate still work?

slon842 Thank you for pointing this out! We will look into our build system and check why this file is left out of signing process.
