Hi,
I've created installers using Advanced Installer 7.6.1 and tested them on Windows 7 (32-bit), Windows Vista (32-bit), Windows Server 2003 (64-bit) and it works flawlessly. But when try to install them on Windows Vista (64-bit) it gives me the message "Another installation is already in progress..." (Retry | Cancel) just after i click the "Install" button. I've tried dozens of things but no avail. Note that this happens from an "advanced" installer with custom actions, services, etc. But also happens with simple installers that basically only install files on the machine.
Note: I've checked that there's no other installation running on background when i try to install them.
A fix is much appreciated!
Thanks in advance,
LaleX
