libreoffice on computer; old file says can only be opened with microsoft office. how to open?
I purchased this hp desktop pavilion in 2014. At the time, my old files were transferred in. Libreoffice was part of the new computer. Now, as I try to open a document from 2012, the computer says it can only be opened with Microsoft Office. Is there any way around this, or must I purchase MS office (or submit to the one month free trial). Seems a waste to have to entertain using MS office for one small document. Suggestions?
