(1st of all, I'm not a native englsih. Please understand my stupid expressions) I make my own Unattended WinXP CDs And some applications are installed by RunOnceEx script I think mine(RunOnceEx) is perfect but *some installers are skipped (Though in installation menu - what is excuted after RunOnceEx.cmd injected n reboot - very looks fine, nothing installed) What is strange, every time I setup whole Windows, skipped apps are different by times (not all apps are skipped, there's *some fixed ones *some : diskeepr, **** nfo viewer) In addition, after all Windows setup over, that some apps are installed fine with manual RunOnceEx registry injection (run edited RunOnceEx.cmd manually, reboot, then install -> works fine ) Here are my RunOnceEx scripts
