Please make sure that you are extracting all the files from the ZIP archive to a folder on your computer. Once you have done so, please ensure that you right click on the IMVU Password Recovery.exe, then run the file as an Administrator. As long as you had previously checked the option to save your password during your last login, the information should be revealed by the program.
