Hello,
I have a problem trying to use administrative setup. My msi file is contained in an exe, and the regular setup runs just fine. But if I try to run administrative setup (via cmd using "c:\setup.exe -a //", as documented), I get the progress bar indicating that setup is extracting files, but when it finishes and the installation should start, I get a message claiming that another installation is already in progress and the setup closes. I do not, however, have any other installation running, no windows updates or anything (this is a virtual machine explicitely for testing the setup, so I pay attention to not having anything else running that could have influence in any way). Restarting the machine does not help, either.
After googling a bit, the common cause seems to be that the user is not an administrator, but this is not true in my case. The user has admin rights, and I tried explicitely running cmd.exe as administrator (right click menu on vista, "run as administrator") as well as creating a shortcut, appending "-a //" to the target and running this shortcut as administrator. No difference here.
This happens with Advanced Installer 8.1 and the recent 8.1.1 update. If I remember correctly, the 6.8 version that we used before created an exe that could be run as administrative setup the same way that I'm trying above.
Does anyone have an idea or a solution to this problem? Am I doing something wrong and just don't see it? If you need further details on anything, just ask here, because I'm not sure which information would be relevant.
Regards,
Chris
