The computers have SSD, SSD/HDD hybrid and a regular HDD. I have tested both versions on 3 computers, one doesn't even have AV installed on it yet, superfresh install.

Here's the thing though: I even compress the Bernat version MORE with the AppCompactor to reduce the size as much as I can and Avast has no problems with that. The program is cross platform with versions available for Mac, Linux/BSD (comes default with most distros) and supports a variety of extensions.

Legacy - for WinXP/Vista users (unsupported).

Still - more tested and stable but with fewer features/capabilities.

Alternatively, X-LibreOffice is also available. can be enabled by adding jPortable, though this is optional and can be skipped if those functions are not needed. On systems without Java installed, some functions such as document creation wizards and the Base database application etc. LibreOffice Portable is a special build developed in conjunction with the publisher. The program is similar to OpenOffice, a program that it was derived from, but has added many new features and improvements. Includes strong compatibility for 100s of file formats including Microsoft Office (Word, Excel, PowerPoint, Visio etc.). LibreOffice is a complete productivity suite including word processor, spreadsheet, presentations, database, drawing tool and more.
