I've Qt SDK which is an offline installer. According to the instructions given for installation, first I have to
chmod u+x Qt_SDK_Offline.run
But when I do ./Qt_SDK_Offline.run, it's saying you don't have permission.
For problem 1
Step1: copy the file to the Desktop or home folder(This is because if the File is on an external drive you have to mount that with execution properties which is not done on Ubuntu by default)
Step2: right click on the file and chose properties ,and check the allow the file to execute button.close
step3:Double click on the program
