Installing sql express and installing on form load is not working

Hi Peeps

I created a project and published it with click once, but got errors because sql express was not installed on the client's pc.

I'm calling the sqlexpress.exe file to install when my form loads - it goes on with the installation and finishes successfully but when I login to my program I get errors, when I go into the folder where the exe file is and I install from there my program works...

Is there an easier way of doing this or am I doing something wrong?

Here is my code :

Process myProcess = new Process();
myProcess.StartInfo.FileName = @"C:\Folder\sqlexpr32.exe";
myProcess.StartInfo.Arguments = "start /wait " + vlNew_SQLExpressFilePath.ToString() + " /qn username=test companyname=testany addlocal=ALL  disablenetworkprotocols=0 instancename=MyInstance SECURITYMODE=SQL SAPWD=test123";
myProcess.StartInfo.UseShellExecute = false;
myProcess.Start();

Thanks in advance
