The default instance of Velixo installs components to both AppData and LocalAppData repositories. If these are locked down by your policies, you will run into this issue.
Windows Security is blocking creating the initial SQLite database file
Often you see no information about this until you repeatedly error out, and then you will receive a popup. This is particularly evident when running Windows Defender.
Eventually, you will get a popup as soon below:
To resolve the error above, TEMPORARILY add an exclusion to allow the EXCEL.EXE process to create the SQLite file, and once created, remove the exclusion.
To add an exclusion, go to Windows Security > Virus & Threat Protection > Settings > Manage Settings > Exclusions > Add Exclusion > Process
Once you have added the Exclusion, attempt to run a process using Velixo Reports, and once successful, remove the temporary exclusion.
