VB open specific Excel Version when two are installed

Question

I am looking at this piece of code that I got from here because I would like to use it. The issue is, I have used 2003 to create the "test.xls" file but when I run this code it opens in 2007. Is there any way to force this to open in a specific Excel version rather than the default?

GoSub, GuiOpen
pweb := COM_AtlAxCreateControl(WinExist(), A_Temp . "\test.xls")
pxlb := COM_Invoke(pweb, "Document")      ; Excel Workbook
pxls := COM_Invoke(pxlb, "Worksheets", 1)   ; Excel Worksheet
Return

GuiOpen:
Gui, +Resize +LastFound
Gui, Show, w800 h600 Center, Excel
COM_AtlAxWinInit()
Return
GuiClose:
Gui, Destroy
COM_Invoke(pxlb, "Save")
COM_Release(pxls)
COM_Release(pxlb)
COM_Release(pweb)
COM_AtlAxWinTerm()
ExitApp

This has to do with the way that file is associated on windows...try this on an open folder:

Tools > Folder Options > FileTypes

Look for the xls file and change which program opens it. If you dont find it simply add it and change its options accordingly.
