Sorry, I do not where I can make a question. I need generate 64 bits application in the new version of Lazarus. I installed theIDE of 32 bits and installed in another directory the add-on for win64. I do not find where in the IDE I must activate the add-on or how is the manner for 64 bits application and the depuration because I generate 64 bits applications before in Lazarus, but the message of release notice that is necessary use 32 IDE. Thanks for your comments.
