Hi. I've downloaded both version 7.6.22 & 7.4.42, and neither will install on my Vista laptop.

When double clicking on the exe files, nothing happens and there is nothing in Task Manager to indicate that the exe is running. I have tried running the installation as an administrator and also tried changing the compatibility, but nothing happens.

Any suggestions would be gratefully received.

Normally, when nothing happens at the start of a Windows Installer, the installer is corrupt and you best redownload a new version to a new directory.

It's also possible another (older) installer is still running, so check in task manager->processes that there are no MSIEXEC.exe and TrustedInstaller.exe processes running. Also check under "running processes of all users".

You have of course checked that your anti-virus or other anti-malware program / firewall isn't blocking the execution of the BOINC installers?
