When I try converting my vcl to firemonkey with mida pro 4.52, the conversion appears to work successfully. However, if I try to open a converted form in XE7 or XE10, I get a message saying "Error = expected in line 144 or some other number" - typically, the line number referred to is either blank or would not have any code where an = sign would be expected. Thoughts on what may be causing this? If I am a registered user of 4.52 pro, is there an easy way to upgrade to 5.2 pro or do I have to pay the full purchase price again?
