Hi Charles
Thank you for your response.
Please see the exact error code attached.
As mentioned earlier and while being the service provider of an IT firm, we checked the control panel and he had Office 2013 installed. We even removed it and restarted his PC, but still the same error.
Additionally as mentioned once again, I tried the installation on my own computer as well which had Office 365, the installation window simply disappears after a few seconds on mine "without" the error. There is no instruction given on what Office you must have or not etc. before installing Project Standard 2021.
Please also see screenshot from where the installer is downloaded from his portal.
Thanks
Moses
