If i want to update my MPLAB IDÉ 7.10 to a newer version must i so uninstall the older version first?? And must i do a backup of all my asm.files there are saved in MPLAB before i do this??
Microchip say you should uninstall any previous versions.
Doing so does not normally delete you work / project files if you have placed them in a sub-directory within the Microchip folder. However you should still copy the folder/s to somewhere safe just to be sure,before uninstalling.
Have done about five full updates of Mplab without any problems - usually takes about 10 mins once you have downloaded it.

Thats true, but it doesn't matter where you keep your files, if your HDD crashes when you are in the middle of a project your are stuffed, as I once found out.
For your key MpLab data files strongly suggest you set up a small automatic daily back up to a cd, dvd or pen drive.
