having bit of trouble azure custom script extension on windows vm. have created script installs particular business application. in order accomplish this, script calls several other scripts , reboot required in between 2 scripts.
the script designed such can "pick left off" checking whether files exist or if registry keys exist. reboot portion of goes fine, however, i'm noticing script handler sets several registry keys keep track of state in
hkey_local_machine\software\microsoft\windows azure\scripthandler
i see registry value called "mreseqnumstarted", presume how script handler keeps track of script it's executing. there 1 script fired extension currently, , value set 0.
what i'm seeing, that, when machine rebooted after script has completed, script fires again. occurs every reboot of virtual machine. believe script extension not marking script "completed", , i'm @ loss why. basic (sanitized) flow of script below:
