File Not Found

[Deepak Sakpal]

This code works on my developement machine but not on clients machine.
I am getting error - run time error '53' File not found MDicInstallCheck.dll.
What the hell is this . MDicInstallCheck.dll is developed in VC (It can't be reffered from Project >> References).
My application's exe & MDicInstallCheck.dll are in the same directory.

Private Declare Function MDicInstallCheck Lib "MDicInstallCheck.dll" (ByVal szCmdLine As String) As Boolean
 
Private Sub cmdCancel_Click()
    Unload Me
End Sub
 
Private Sub cmdOK_Click()
    Dim strCmdLine As String
    strCmdLine = Chr(34) & "{" & txtKey.Text & "}" & Chr(34) & " " & txtHide.Text
    
    If (MDicInstallCheck(strCmdLine)) Then
        MsgBox "Registration Complete. Activated Installation", vbInformation, "MRecord 2004 PRO Release 3"
        MsgBox "Thank You for Installing MRecord", vbInformation, "MRecord 2004 PRO Release 3"
        End
    Else
        MsgBox "Invalid Entry, Try Again", vbExclamation, "MRecord Release 3 Setup"
    End If
End Sub
 
Private Sub Form_Unload(Cancel As Integer)
    Shell (App.Path & "\PV.exe -k -f msiexec.exe")
    MsgBox "Installation Aborted", vbInformation, "MRecord Professional Setup"
    End
End Sub
