I have Perl applications which read and write to spreadsheets. I am using MS Office 2010 to write spreadsheets which are read by the applications.

I use the following Win32 modules: 

use Win32;
use Win32::OLE;
use Win32::OLE::Const "Microsoft Excel .* Object Library";

[download]
Office 10 support ended last month (October). I think that Office was automatically updated at the end of October. When I try and start either Excel or Word I am getting messages like "Error 1706. Setup cannot find the required files" but it they will run when I use a Cancel option a number of times. I am not confident that if I solve this particular problem I will be able to do so if more arise in the future.

Rather than buying one of the versions of Office I am looking at the free alternatives such as LibreOffice. My initial tests seem to show that this can read and write .xls and .xlsx formatted spreadsheets.

Some questions:

Q1. If I use LibraOffice can I still use the Win modules listed above? If so is this likely to remain the case for at least a few years?

Q2. Are there any particular hidden traps that I should be aware of?
