Software Requirements problem

[geppo12]

I Cannot add a software Requirements which look for a specific key on Registry. Moreover I am confused about the "64 bit part of registry" checkmark present in the wizard.

I answer all question of the wizard, I have that key in my registry, but if I enable that software Requirements, the installation fails.

Thank for help

When using a Registry Requirement as you have defined:

HKEY_CLASSES_ROOT
SOFTWARE\Microsoft\SQL Server

When the Value is left blank, this causes the installation to look at the data of the "(Default)" value of that registry key. If the "(Default)" has no value, or is empty, Windows Installer considers this as the key not being present.

So if there is no "(Default)" value for a registry key, the condition will fail. Unless you are specifically checking for the "(Default)" value, it is usually best to look for a specific Value.

Hope this helps
