problem with reader

Hi every one can anyone help this year 2020 January my adobe reader ver X has started closing down 15 seconds after opening I Know its out of date but its the version that allows me to sign a document with an image of my signature and able to lock it after wards.

The strange thing is it has happened to all of my computors at the same time I am running 3x win 7 and 1x win 10 and none of them have updated .
