Hi...RunOnceEx.cmd does not run on my Windows 2000 VMware Control Panel install from ISO. A post on msfn forum gave me the way to detect what the problem was. After each entry is an error notice: This I should have realized because I ran into the same thing when I first started testing each RunOnceEx entry and had to install the Windows 2000 Support Tools CD package. Searching the forums as to how to do the same thing for an unattended CD located this post: http://www.msfn.org/lofiversion/index.php/t39896.html on the very subject. It stated: I've done this and it didn't work. Yes, reg.exe was there in the VMware OS winnt but it never served any purpose other than take up space. I suspect very strongly it takes more than just placiing reg.exe in winnt. Isn't their some kind of file association that a registry entry arranges say, in this case, between RunOnceEx.cmd and reg.exe so when the REG command is encountered, reg.exe can do it's number correctly? Or do I have to include the entire 10MB Support Tools package in my ISO build and run the setup.exe in a batch file that will install all the support tools before RunOnceEx.cmd is run? After some 15 ISO builds and VMware installs I'm out of other ideas and this is the first solid lead I've come up with. Unfortunagely a search for just reg.exe turns up nothing and including "Windows 2000" or "install" turns up a zillion anwer pages. Any help in getting reg.exe active in Windows 2000 would be appreciated. Regards, Nick
