If there is no modify path under the applications name then check through each GUID for the programme concerned.
Copy contents to command window and change the /I for a /X if neccessary.

You can also use this command on any MSI install package including drivers:
MsiExec /x ‘c:driversWin_x86_SES_Driver.MSI’
