Hi, so for automation anywhere client installation, in the registry under HKEY_CLASSES_ROOT you'll find the folders as shown in the screenshot
If you're on a distributed enterprise installation, you'll likely also find another related entry under HKEY_CURRENT_USER > Software > Automation Anywhere.
win key + r > regedit and navigate through there to get to these entries.
I would also like to recommend you to undergo Intellipaat's Automation Anywhere Certification to get certified in this RPA tool.
