timeout issue

hello,

i need help here.

i have two laptop.

laptopA, laptopB. I have portable version of teamviewr on laptopA (because I don't have write to install .exi on it). On laptopB i have teamview10, when i connect from laptopA to laptopB my session gets terminated after around 3-4 minutes with timout message. 

i upgraded teamveiewer version on laptopB to 14 but then i was not able to connect due to target machine (laptopB) having higher version than source (laptopA)

I alwayse need to connect from laptopA to laptopB. 

Please suggest how to sort out timeout problem?
