"Component transfer" error means that the installer cannot copy files to the Essential Forms program folder or data folder. It can be caused by someone else on the network opening the program during an install, a bad network connection, or a file in one of the Essential Forms folders set to read-only. Reboot the computer, make sure all users have Essential Forms closed, and try to run the install again. If a specific file is mentioned in the error message, check that file by browsing to it in Windows Explorer, right-clicking on it and selecting "Properties", checking to see if "Read-only" is checked (if so, uncheck it and click OK). If that doesn't work, try temporarily disabling any anti-virus software to ensure it's not blocking the installer.
