Set attribute for desktop software

Hello everyone, i am trying to set an attribute for a table which has a field to check/unchecked. I need to do this without using click because sometimes there are rows not visible so the bot cannot click these. I tried with set web attribute but this can be used only for browsers, and is not my case. I would really appreciate any help you can give me.

give a try on using click along with simulateClick option
Another option could TypeInto to the check box with the SimulateType Option = True and a space " " as its value

you mean simulateClick set to true? I tried with type into using simulateType option but it says the control did not recognize that method.

find some additional information here:

maybe the technology falls into the unsupported category
