This thread does’nt help me 
I try many things …
clean registry
uninstall + Install again the last version in the default path
uninstall + Install again the last version in another path c:\avast4
…
for each exe file (ashAvast.exe an all other ),
i have always the message : Application Error - The application failed to initialize properly (0xc0000005)
All others applications are working.
