Ron, I think your best bet is to load UFT on the old system then make a backup .sqz file of your data on the laptop and then restore on the desktop. Put the backup on your HD then copy to a CD if that is your only method of transfer.
I set up UFT to use WP10 and found that WP10 could not open the .rtf file it was sent. WP10 did open. So I tried again with the auto launch editor unchecked. Saved the file as a .rtf then used WP10 to open the file and it opened.I gave up on the use of WP for UFT files long ago and use Word. But WP is my normal program so needed 10 to work on XP.
