Hi All, I Had the same problem, I have a fix partially. I have edited the msi install file and removed 1 line. The line that starts up kaspersky anti virus. See the attachment And the installer does not reboot after install. The only thing is that kaspersky implented that the system needs to be rebooted when you start up kaspersky anti virus the first time. So concluding the fix I did doesn't require reboot at install, only at first run time. And I think this also applies to Kaspersky internet security. Greetz!
