Problem with CmdAfter (General questions)

wodAppUpdate version 1.3.1.86

Config file:
#Update file signature

[Global]
CmdAfter=c:setup.exe

[File]
Name=Setup.exe
Path=c:setup.exe
URL=file://I:My AppsSETUP.exe
MD5=0866635.....

After Update, the file Setup.exe is copied correctly in c: but does not run.

Any ideas?

Thanks
