Issue with uninstall and install program

Hi There

I have contact MYOB yesterday because we are having issue updating the program. They sent us a link and told us to first back up the fiel and than uninstall the old MYOB, afterward, click the link they provide and install the program.

However, we have trouble uninstall the program just like last time. As this is not the first time we have this issue.

Please E-mail me back with step by step solution.

Thanks
