If not, put it in another laptop and see if it works (it probably won't).
I used the Microsoft Office encryption for an Excel 2003 spreadsheet. The computer crashed, but the HDD is fine. I don't have another computer to put the HDD in, but I do have an HDD enclsoure. It's a SATA HDD. For the file to open, It has to be opened from the copy of Excel on the HDD. Does anyone know how to open Excel on an external HDD without jumping over to the laptop I'm using. Any other ideas would also be greatly appreciated. Thanks.
