The System Search Wizard and the System Search view enable you to configure the following types of registry-related system searches:
| • | File path, as specified by a registry entry |
| • | Folder path, as specified by a registry entry |
| • | Registry entry |
Note the following details about these types of system searches.
Searching for the Presence of a Registry Key
Windows Installer does not have built-in support for searching target systems for the presence or absence of a specific registry key. However, you can create a system search that looks for the default value of a specific registry key. If the default value is present, Windows Installer writes it to the system search’s associated property. If the system search fails to find the default value, Windows Installer leaves the property undefined.
Storing Registry Entry Types in a System Search’s Property
At run time, Windows Installer sets the value of the property that you specified for your registry-related system search to the location that is found on the target system. In addition, Windows Installer adds a prefix to the property value to indicate the type of registry entry (such as REG_DWORD or REG_BINARY). If you then use the property to configure the registry, or if you create a condition that reads this property, you must understand the syntax that Windows Installer uses to set the property.
The following table lists each of the types of registry entries, along with the associated prefix that Windows Installer uses when setting the system search property.
|
Prefix/Notation |
Meaning |
|
<No prefix> |
The property value contains a string value (REG_SZ). |
|
# |
The property value contains an integer value (REG_DWORD). |
|
#x |
The property value contains a hexadecimal value (REG_BINARY). Windows Installer converts each hexadecimal digit as an ASCII character for this property value. |
|
#% |
The property value contains an expandable string value (REG_EXPAND_SZ). |
|
<null> |
The property value contains a list of strings (REG_MULTI_SZ). This value starts and ends with null. |
