Ok so I wanna play with some spreadsheets. Lets see. Lets copypaste from  
the pickaxe.

Ruby replies:  
myExcelApp.rb:9:in `initialize': unknown OLE server:`Excel.Application’  
(WIN32OLERuntimeError)  
HRESULT error code:0x800401f3  
Invalid class string from myExcelApp.rb:9:in `new’  
from rudumapponator.rb:9

Ie. no joy. Something wrong with the Win32Ole library?

Your code works fine for me on irb on win xp.

Can you actually open a ‘genuine’ xls file on your machine to see if  
ms-excel/office is working properly? I’ve had problems before where  
win32ole wouldn’t work b/c the ms-office software license had not yet  
been activated (don’t remember what the specific error was, tho).

Ah! _slap forehead_ So I need a excel license installed on the machine??

That would explain the problem. Silly me! I guess I will need to turn to  
Open Office…
