Executable signature verification failed

[polygonweb]

The following error messages appear :

"Executable signature verification failed"
"Cannot load 'Content/Talos/SignatureCatalog.dat' : block signature verification failed"

I have tried all the solutions of the FAQ, but none of them works. The certificate seems to be ok. Here is my log. Thanks !

Hmm. Are you really sure that you have verified the cache? Try deleting a file, like the exe, and verify the cache again. Something was downloaded wrong, it seems.

[polygonweb]

Yes, I verified it. I tried your solution, it doesn't work :(

[AlenL]

Have you checked the FAQ's entry about digital signatures on executables?

[polygonweb]

Yes. "Talos.exe" has a valid digital signature.

[AlenL]

I supposed it is signed by Valve Corp? Also, can you please check digital signature of steam_api.dll (in the same folder)?

[polygonweb]

I checked steam_api.dll and indeed, its signature wasn't valid. Now everything works. Thanks ! \o/
