Just to clarify, XDK crashed and when you reopened XDK all your apps were gone from the menu?
If this is the case, you should still be able to re-upload those apps by:
It may be a bit tedious but if you've saved them onto your computer they are still recoverable.
OK but if have backup copy of hdd can recover an xdk "system" file and All apps get recovered?
note : some apps Not remember their location in hdd...differ from default location.
Leonidas -- try downloading the installer directly from http://xdk.intel.com and running that, instead. Remember to exit the XDK before attempting to run the installer. Let me know if that fixes the issue.
soon to do
About the recovery of Apps -- may forgotten where are in disk, so can recovered by substitute a xdk system file... i have whole hdd backup from September 2016....?
you mean there is no file xdk (to copy from backup) for projects be like was(all recovered at once)?
where projects saved in xdk?
about Android & iOS certs saved when login in intel account?
The XDK does not "save" your projects anywhere, it simply references the projects as folders on your hard drive, we do not manage where you locate your projects or how you back them up. Those projects that are pushed for a build or for use with the Test tab contain only the source of your project, not the XDK file, and are stored only temporarily on the build system. If you have a copy of your built app (for example, the APK file) you can open that to get the same sources, it is a ZIP file and can be unzipped on your hard drive.
Reinstalling the XDK has no impact on the location or state of your projects. As indicated above, the XDK just references folders on your hard disk, it does not store or manage your projects, that is your responsibility.
