Hi, I have my multiboot DVD and I did like to run some install programs just after the Windows installation, at the first logon (see the screen copy in attach file at this post) So, in the http://gosh.msfnhosting.com/using_runonceex.htm article, I seen the infos about "runonceex.inf" file BUT : - What is the location of this file ? Where I must place it ? - How I do to run it automatically ? By example, if I put manually the HKLM -> RunOnce -> install01 (dword) with the value e:\setup\mysofts\reader7.exe (note "runonce" and NOT "runonceex" key), it's good, perfect ! THANKS TO ALL FOR YOUR HELP
