Thanks
I worked in another way, used the event viewer of Windows.
The moment the program stops I receive the following messages in the eventviewer:
Activation context generation failed for "C:\Program Files\Avast Software\Avast\RescueDisk\aswPEAntivirus.exe". Dependent Assembly avast.local_vc142.crt,processorArchitecture="amd64",publicKeyToken="b7b3b11e08ac5c30",type="win32",version="14.0.0.0" could not be found.

Please use sxstrace.exe for detailed diagnosis.
Any suggestions?
