LibO 3.4 and 3.6 on windows and Linux will not display math equations in write or impress from docs saved in .docx and .pptx respectively . I tried O.O. 3 as well with same result. I need these functions desperately. Please help.
As I tested, MS Equation objects are shown in .doc & .docx files in LibO 3.5 - 3.6 and AOO 3.4 in Windows XP 32 bit. May be problem is with your files. Can’t say anything about MS Equation objects in .pptx format (not tested by me).
