Commented Unassigned: Product key dialog shows up during installation ? [22015]

Hello

I want to install a simple single server farm SP2013 Enterprise with your script, and after following all the instructions, Unfortunately at the " - Installing SharePoint 2013 binaries......." step the Product key dialog shows up as shown on the screenshot. Why this is happening ?

Shouldn't the installation proceeds by itself and picks the PIDKey value from the XML file? Why it doesn't?

One-Single farm info:
OS: Windows 2012 R2
SQL Server 2012 SP2
SP2013 media: SP1 Slipstream (Meaning the downloading ISO from MSDN contains SharePoint with SP1 together)

<Configuration Environment="SP2013Farm" Version="3.99.51">
<Install SPVersion="2013">
<ConfigFile>SP2013Farm.xml</ConfigFile>
<InstallDir>C:\Program Files\Microsoft Office Servers</InstallDir>
<DataDir>C:\Program Files\Microsoft Office Servers\SharePoint2013\Data</DataDir>
<PIDKey>MY-100%-CORRECT-KEY-VALUE</PIDKey>
<SKU>Enterprise</SKU>
<OfflineInstall>false</OfflineInstall>
<PauseAfterInstall>false</PauseAfterInstall>
<RemoteInstall Enable="false">
<ParallelInstall>false</ParallelInstall>
</RemoteInstall>
<AutoAdminLogon Enable="true">
<Password>Password</Password>
</AutoAdminLogon>

Could you please help out? Am I doing anything wrong?

Thank you !

Right, so you've self-referenced the XML file you used for the entire farm build as the *config* file for the installation of SharePoint 2013 itself. They are two different things. Therefore when SharePoint goes to kick off the installation, it looks in your AutoSPInstaller "SP2013Farm.xml" file for a product key but the file isn't in the format expected - so you get a prompt for the product key. To get straight to resolution, try putting some other value in, for example:

<ConfigFile>Config.xml</ConfigFile>

And the install should proceed.
