• The “Not a valid Win32 application” issue can be caused by a couple of things:
• File is corrupt, bad, or missing.
• Hardware incompatibility (maybe, can happen but not as likely as a bad file).
If the Legacy setup file is corrupt, incomplete or missing, Windows will be unable to execute the file and may generate this error message, or other messages.
1. Reboot your computer and try installing again. If you still get the error go to step 2.
2. Download and save setup file to your Desktop screen. (If you had previously saved this file, delete it before downloading it again.)
LEGACY: http://www.legacyfamilytree.com/DownloadLegacy.asp
LEGACY 7.5 OR EARLIER: http://support.legacyfamilytree.com/article/AA-00899 and download the final release (build) of your version. You may also wish to read "How to Install Legacy 7.5 or earlier on a Windows 8, Windows 7 or Windows Vista computer" at http://support.legacyfamilytree.com/article/AA-00897.
3. Next, reboot your computer in Safe Mode and temporarily disable your security programs (firewall, anti-virus, anti-spyware, anti-adware, popup blockers, etc.) as these programs can sometimes remove critical system files from Legacy.
4. Install Legacy using the saved Legacy setup file.
• Installing a program from a CD or other disk
1. If you're attempting to install a program and are getting this error, verify that the CD is clean. If the CD is dirty, scratched or bad, you could get this error during the install and/or get this error after the program has been installed because it was not copied properly onto the computer.
2. If you're still getting this error after carefully cleaning the CD, it's also possible that the CD-ROM drive or the drive you're installing the program from is not compatible with Windows or has drivers that are not compatible with Windows.
3. Download the latest drivers for your CD drive from the manufacturer's Web site.
