Program performed illegal operation while renaming .new to .exe

[topone]

Hi,
I am getting an error - program performed illegal operation - exception 10h in module msvbvm60.dll when program checks for new version on server if exists downloads the program by closing the current program

1. App.exe -- calls AppUpdate.exe using shellcode
2. AppUpdate.exe terminate app.exe
3. Then check the version differences, if new version exists on server downloads using ftpdownload file named app.new.
4. filecopy app.new, app.exe,true - copy app.new to app.exe by overwriting the already existing file app.exe.
5. once all above is sucessful delete app.new and runs app.exe

In this process error occurs with above details. This happens at client place not in the development machine

Hope to get solution soon
Thanks

Excellent. So now how us how you are "call[ing] AppUpdate.exe with shellcode

 

[topone]

Dim SEI As SHELLEXECUTEINFO
Dim ProcessHandle As Long, i As Long
Dim ConHandle As String

UpdateClient = False

ProcessHandle = MDIFrmMain.hwnd

'Fill the SHELLEXECUTEINFO structure
With SEI
.cbSize = Len(SEI)
.fMask = SEE_MASK_NOCLOSEPROCESS Or SEE_MASK_INVOKEIDLIST Or _
SEE_MASK_FLAG_NO_UI
.lpVerb = "Open"
.lpParameters = ProcessHandle & " " & HndCon
.lpFile = App.Path & "\appUpdate.exe"
.nShow = SW_SHOWNORMAL
End With

' execute
ShellExecuteEX SEI

AddStatusText "Updating app newer Version ..."
UpdateClient = True

End Function

I think we need to see your declarations for ShellExecuteEx and the SHELLEXECUTEINFO structure (given that what you have here so far looks OK)
