I not said that "you need change the office suite".No way to change Program.
You can try the portable versions without any problem. Just unpack and copy the files from the zip archive to the target program directory - you can choose where it will be - without any "regular installation" procedure. The portable version of the LO will not uninstall, delete, destroy or modify the permanetly installed AOO or LO versions (nor its settings). You can use it paralell with the permanently installed version/s/.
As you can see in my signature: as a helper in this forum, I am using paralell many portable versions in my Win7 and Win10 (prof x64). In this way I can try the problematic files with the relevant version of the AOO/LO.
