Linux Mint: Qt Creator (Community) Correcting Launch Path

[chwa]

I'm a Linux Mint 17.3 newbie. Originally I installed QtCreator under my /home/chwa/ directory. I am trying to correct my mistake and install QtCreator in the /opt/ path.
I have:
- Installed QtCreator as root in the /opt/ path
- Deleted the /home/chwa/Qt5.5.1 folder
- Have everything working correctly for regular Qt Creator
BUT I cannot access Qt Creator (Community). When I try to open it, it says "Failed to execute command '/home/chwa/Qt5.5.1/Tools/QtCreator/bin/qtcreator'". Obviously this is because I deleted the /home/chwa/Qt5.5.1 folder. How do I change the '/home/chwa/Qt5.5.1/Tools/QtCreator/bin/qtcreator' directory to 'opt/Qt5.5.1/Tools/QtCreator/bin/qtcreator'?
