This is interesting. Others have same issue. I have never had issues installing GIS Server or Portal before. Upgrading to new hardware, so starting from scratch. Remember it took forever to uninstall Portal on older hardware, so used command line for that and the new install on new hardware. Used this: Documents\ArcGIS 10.8.1\PortalForArcGIS\SetupFiles>msiexec /i setup.msi /Lieux C:\temp\GISportal_install.log Then it froze with MSI not responding. Hit retry and finally started again. Now it seems to have stopped at green bar at 65%. The last 2 lines in log are: Action ended 9:58:39: SetFIX_UNINSTALL. Return value 1. Action start 9:58:39: InstallInitialize. That was 20 minutes ago. the only thing I can think that is different is our outsourced IT has installed BitDefender Endpoint Security, but ArcGIS Server installed (but slowly with the same retry popup) OK. maybe there will be another retry popup I can hit.
