I upgraded from PB 2017 R3 Build 1880 to Build 1915 (PWRBLDR-2017R3LTS-MR07-1915-EN) but now PB is not running.

When I install the new build I get the following message:

---------------------------
Self-Registration Error
---------------------------
The following files did not self-register or unregister:
1. C:\Program Files (x86)\Appeon\Shared\PowerBuilder\PBNAT170.DLL
El parámetro no es correcto.
2. C:\Program Files (x86)\Appeon\Shared\PowerBuilder\pbwsdlclient170.dll
El parámetro no es correcto.
To continue, click OK; otherwise, click Cancel.

Once the installation is finished I run PB 2017 R3 and I get the following message:

---------------------------
PB170.EXE - Imagen incorrecta
---------------------------
C:\Program Files (x86)\Appeon\Shared\PowerBuilder\pbsys170.dll no está diseñado para ejecutarse en Windows o contiene un error. Intente instalar el programa de nuevo por medio de los medios originales de instalación, o póngase en contacto con el administrador del sistema o el fabricante de software para obtener ayuda. Estado del error 0xc0000045.

Translated:
C: Program Files (x86) Appeon Shared PowerBuilder pbsys170.dll is not designed to run on Windows or contains an error. Try installing the program again using the original installation media, or contact your system administrator or software manufacturer for assistance. Status of error 0xc0000045.

Any solution?

Thank you.

RESOLVED:
This whole problem has been generated by the temporary blocking of the Panda corporate antivirus. Once the dll's have been checked, the antivirus works perfectly.
