Oh, sorry, I actually found some related info: http://en.wikipedia.org/wiki/Windows_Script_Host > By using *Software Restriction Policies* introduced with Windows XP, a system may be configured to execute only those scripts which have been digitally signed, thus preventing the execution of untrusted scripts. So, if someone disables it, it won't work...
I wouldn't use JS if it wasn't absolutely universally available and pre-installed - that's why I first asked :) I thought that scripting host component is the part and parcel of Windows, just wanted to be sure. OK, I will comment on the bug too, it's just not strictly related, that's why I asked here. Best. Oleg
