NSIS script to install an exe which requires a Registration Name and Key to be set - executable

Question

Problem: I need to write a nsi for doing a series of tasks including creating a folder, some IE settings changes, Firewall changes and Installing an exe. The exe to be installed is a licensed copy and requires a Registration Name and Key which I have.
Scenario: I need to perform the same steps after installing the exe in more than 50 computers and I want to make the process free of manual errors.
I successfully wrote all steps but still to find how to install the exe, which prompts me for a Registration Name and Key.
Thanks

Can you explain how do you plan to handle the registration name and key, will you need a server to validate the installation ?
Anyway you have to make a custom page and create custom forms in this page. Something like :
Page custom CreatePage QuitPage
Where CreatePage is a function that creates the page ui
Example:
;;In the variables section
var regname_hdl
var regkey_hdl
Var regname_inpt_hdl
var regkey_inpt_hdl
var RegName
var RegKey
Function CreatePage
GetDlgItem $0 $hwndParent 3
EnableWindow $0 0
nsDialogs::Create 1018
Pop $Dialog
${If} $Dialog == error
Abort
${EndIf}
${NSD_CreateLabel} 0 0 100% 10u "Say something to user"
Pop $Label
${NSD_CreateLabel} 20u 20u 20% 20u "Enter Registration Name "
Pop $regname_inpt_hdl
${NSD_CreateLabel} 20u 40u 20% 20u "Enter Registration Key "
Pop $regkey_inpt_hdl
${NSD_CreateText} 30% 20u 30% 10u ""
Pop $regname_hdl
${NSD_CreatePassword} 30% 40u 30% 10u ""
Pop $regkey_hdl
nsDialogs::Show
FunctionEnd
Function QuitPage
${NSD_GetText} $reg_hdl $2
${NSD_GetText} $key_hdl $3
Push $3
Push $2
Pop $RegName
Pop $RegKey
${If} '$2' == ""
messageBox MB_ICONEXCLAMATION "Reg name is empty !"
Abort
${ElseIf} '$3' == ""
messageBox MB_ICONEXCLAMATION "Reg key is empty !"
Abort
${Else}
System::Alloc 9
Pop $4
;; Here you have to call some procedure to check if reg name and key are valid
;; let's say the procedure returns 1 for true and 0 for false and it stores the result in $1
${If} $1 == 0
messageBox MB_ICONEXCLAMATION "Installation denied !"
Abort
${EndIf}
${EndIf}
MessageBox MB_OK "Installation allowed !"
SetPluginUnload manual
System::Free 0
FunctionEnd
