12 errors during upgrade from version V11.0.0 to version V12.2.3

Hi,
During upgrade from version V11.0.0 to version V12.2.3, 12 errors occured (log file attached).
How to fix this easily ?

Hi,

We have no history because of no more ProjeQtor administrator at all.
We can suppose that only the first installation (V11.0.0) has been done.

We can suppose this is the first update.
To update ProjeQtor as indicated in 'readme_install V12.2.3.txt', we placed the new version's zip file on SRV-APP in this location:
"C:\wamp64\www\projeqtorV12.2.3.zip"
Then we ran 7-zip -> Extract here.
This forced the replacement of the files/folders present inside the folder:
C:\wamp64\www\projeqtor

We then ran the ProjeQtor application in a browser and some basic tests were OK (creating new tasks, reading reports, saving imputation, ...).

What do these errors in the update log mean and how to remove these errors easily?
Thank you for your help

Hi,
The previous ProjeQtor administrator left and I'm trying to take over, I assume V11.0.0 is the initial installation.

As indicated in 'readme_install V12.2.3.txt',
to update ProjeQtor, we placed the new version's zip file on the server in this location:
"C:\wamp64\www\projeqtorV12.2.3.zip"
Then we ran 7-zip -> Extract here.
This forced the replacement of the files/folders present inside the folder:
C:\wamp64\www\projeqtor

After launching ProjeQtor in a browser, a few basic tests were all OK (creating a new task, reading reports, recording duration taken, etc.).

Thank you for your help in quickly removing these errors from the log.
