A program required for this install to complete could not be run. Contact your support personnel or package vendor."I think I got this message after deleting several files. I was trying to do a complete uninstall before installing the software again. So, can anyone help here? What should I do?***Updated by moderator: Lochan to branch reply and create new post*** Robotic Process Automation ×Close popoverFacebookTwitterLinkedinEmail Copy Link Copied!
