I developed an application using VB.NET and for install it on other computer, you must first install the SQL SERVER.
I use INNO SETUP for compilation
I chose SQL SERVER as a component in the instalation.
This is what I want to do


Run SQL SERVER with code. I've written:

[Run]
Filename: {tmp}\SQLEXPR32_x86_ENU.exe; Parameters: "/q:a /c:""install /l/q"""; Check: not IsRequiredDotNetDetected; StatusMsg: Microsoft Framework 4.0 is beïng installed. Please wait... 

The extraction of the file was successful, but when the exection begun I get the following error

SQL Server Setup has encountered the following error:  The argument '/Q:A' is formatted incorrectly.  The delimiter '=' is missing.  Error code 0x84B40006

I found some code on this page
http://msdn.microsoft.com/en-us/library/dd981032(SQL.100).aspx[^]

I tried to integrate the following code but it still does not work again.

Filename: {tmp}\SQLEXPR32_x86_ENU.exe; Parameters: "/q /Action=Install /Hideconsole /Features=SQL,Tools   /InstanceName=SQLExpress /SQLSYSADMINACCOUNTS='Builtin\Administrators'  /SQLSVCACCOUNT='<DomainName\UserName>' /SQLSVCPASSWORD='<StrongPassword>'"; Check: not FoundsSql; StatusMsg: SQL SERVER 2008 is being installed. Please wait... 

Can you help me?
