How can an 'uninstall latest update' work?
Dear experts
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 |
| TemplatesWithAdobeFonts\ | structre\ |
| CQPreference.xml |
Although fminit does not contain any backed up dlls, dlls have been exchanged in the process of updating. For example, fmres.dll:
| build | date | size |
|---|---|---|
| 361 | 2017-01-18 | 2'842'752 |
| 406 | 2017-04-10 | 2'842'752 |
| 425 | 2017-06-14 | 2'843'784 |
| 500 | 2017-11-19 | 2'844'664 |
| 511 | 2018-03-08 | 2'836'992 |
Now my questions (to Adobe) are:
- Where is the installation (update) log located?
- How can an update be undone with such a rudimentary backup?
- How are the dlls of a previous build reconstructed, if not available in the backup?
- Does an FM-update place information also elsewhere (then the backups)?
Some insight into these mysteries are welcome!
