Hi everyone! I use win 10, 32 bit java and libre office. Unfortunately I am unable to install LT, see the picture.
Please try with 64-bit Java. LT uses some internal libraries (for spell checking) that are only available for 64 bit.
The thing is I installed both 32 and 64 bit java (because of the problem).
Have you configured the 64-bit one in Options -> Advanced in LibreOffice? Just having it installed is usually not enough, its path needs to be known to LibreOffice.
Try to reset your user profile. It may be corrupt.
