DirectX authentication

[d_a_r_k]

Hi folks I'm creating a WindowsForm application and I need a code to check target's machine installed version of DirectX.
If the reg key doesn't match with provided one >>> load the form and launch the DX installer "redist\directx_Jun2010_redist\DXSETUP.exe"
If the reg key matches with the provided one >>> launch other application "Setup.exe"

Any help would be appreceated

Provided version:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectX]
"Version"="4.09.00.0904"

 

[d_a_r_k]

I really hate to do this but BUMP*

regkey = Registry.LocalMachine.OpenSubKey("SOFTWARE\Microsoft\DirectX", True)
ver = regkey.GetValue("Version", 4.09.00.0904) 'this is where I get end of statement expected error
If ver < 4.09.00.0904 Then 'this is where I get end of statement expected error as well
