Recently I tried to install Wise Package Studio and got the following message. "The system administrator has set policies to prevent this installation".

For my particular instance it was fixed by changing a value in the registry under

HKLM\Software\Policies\Microsoft\Windows\Installer

Name - DisableMSI Type - REG_DWORD 0 = enable

This was originally set to 1.

Hope this helps out someone else who comes across this error.

During my search I also found that there is a Windows Installer 2.0 Bug which sometimes throws up this message. If there is a trace of an application previously having been installed, and you are trying to re-install it, you may get the above error. You can fix this by going to the registry to:

HKEY_CLASSES_ROOT\Installer\Products\

Browse through and find your product. Delete the key relating to your product and this should allow the application to install. I haven't had the opportunity to check this out. But just in case someone is reading this and might need this resolution give it a go.
