With FM-14 (2017) I have discovered the following:
Any of the 4 backups ($HOME\backup_2017.0.1, …2, …3, …4) contains only the following items:
|sub-idrectory in backup-dir||contents|
|fminit\||configui\, workspaces\, structure.fm ➔ no dll|
|structure\||sgml\, xml\, samplesStructapps.fm, structapps.fm|
Although fminit does not contain any backed up dlls, dlls have been exchanged in the process of updating. For example, fmres.dll:
Now my questions (to Adobe) are:
Some insight into these mysteries are welcome!
To answer some of the question you asked,
1.Where is the installation (update) log located?
Logs can be collected using log collector: - https://helpx.adobe.com/creative-cloud/kb/cc-log-collector.html
2.How can an update be undone with such a rudimentary backup?
There is a backup folder which has list of dll's/exe being modified. However, it is advisable to always uninstall and then sequentially updates can be applied to the main product which has been released.
3.How are the dlls of a previous build reconstructed, if not available in the backup?
We can reinstall FM released build and then apply desired update.
4.Does an FM-update place information also elsewhere (then the backups)?
No, this is only in backup folder
Thank You, Amitoj for Your answers.
In the meantime I have found the location of the installation logs (C:\Program Files (x86)\Common Files\Adobe\Installers) with both logs and uninstall data bases. Together with Your information I got the broad pictur of the installation/uninstallation process.
