Hi all, I have recently moved to the latest version of AutoIt, and I see that "RunAsSet" is now history, and I am wondering how I can still do multipal tasks with a limited user logged on, and use the Administrator creditals? I have provided a small sample of what I used to do. RunAsSet("Administrator", @Computername, "password") SplashTextOn ( @ScriptName, @LF & 'Applying fix, please wait...', 350, 70, -1, -1, -1, "Times New Roman", 12 ) FileMove("C:\Documents and Settings\Administrator\NTUSER.DAT", "C:\Documents and Settings\Administrator\NTUSER.DAT.old") FileCopy ("C:\Program Files\Microsoft Office\Office10\ACCWIZ.DLL", "C:\Windows\system32\", 1) RegWrite ('HKEY_LOCAL_MACHINE\' & 'Software\Microsoft\Shared Tools\Proofing Tools\Custom Dictionaries', '1', 'REG_SZ', 'D:\USERDATA\' & @UserName & '\Application Data\Microsoft\Proof\custom.dic') RunAsSet() SplashOff () MsgBox (0, @ScriptName, 'Fix has been applied.', 15) Working on the understanding that "RunAs", only works by calling external exe's, bat's etc I am stugglying with what to do now... I can already hear some of you saying go back to the old version, but i would like to keep moving forward with the new version of AutoIT. Any help greatly appreciated.
