SYMPTOMS
In Microsoft Windows Installer, when your package uses the AppSearch action and the RegLocator table to search for a REG_MULTI_SZ value, the AppSearch action incorrectly truncates the REG_MULTI_SZ value. This problem occurs if the REG_MULTI_SZ value contains a null value.

<div class="cause_section">

CAUSE
This problem occurs when you run the installation in the full UI mode. In the full UI mode, the value that is passed from the client to the service is incorrectly truncated if it contains a null value.

<div class="workaround_section">

WORKAROUND
To work around this problem, use one of the following methods:  Do not use the AppSearch action to search for a REG_MULTI_SZ value that may contain a null value. Instead, use a custom action.</li> Run the installation in the limited UI mode or in the basic UI mode by using the following /qb switch at a command prompt:

msiexec.exe /i  /qb

</li></ul>
