Minecraft addon install error

Hello. I am having this problem for some days. Whenever I try to install a minecraft modpack, it installs for sometime then it gives two error. The first one is ‘Addon install error’ and the second one is ‘Profile error’. Both the errors states “addon instance has no full path!”. For this I can not play any new modpacks. If you can help me out, i will be very grateful. Thanks in advance.
