When the user upgrades to a newer version with the auto updater, but installs to a different location than the older version, after the installation is done, the auto updater shows: "Error: Update installation failed".
My updater ini file (updates.aiu) uses the file version of the exe to check for updates:
FilePath=[APPDIR]jaman.exe
Version=0.80.10.854
I suspect what happens is that the updater checks in the old app path whether the exe has the latest version, but since it is installed in a different folder, the exe is not found and it thinks the update failed.
