I have a similar problem. I downloaded and installed the free trial of the Technical Communication Suite without incident. But I expected to see a Technical Communication Suite icon or shortcut or something - somewhere to launch the thing. There is nothing. I'm not finding any "getting started with" files online, either. I was initially excited to come across this product, as it seems it might be the perfect solution for my team. But I'm kind of lost now. BTW, I have Creative Cloud. In case that means anything.
The technical communication suite is a bundle of several products, rather than a single application. You should have Robohelp and Framemaker applications installed (and possibly something else? but I haven't used the suite, so unsure). Check in your start menu under A for Adobe (that's where the plain Robohelp application is listed). Otherwise try under R or F for the individual products, or T in case the suite bundles them all in a folder.
It's the same as Microsoft 365 (Office), the products are installed but no home page, unlike Microsoft Works if you remember that far back.
My site www.grainge.org includes many free Authoring and RoboHelp resources that may be of help.
