Remove installation kits' dependency on write permission to root C:\.
Some organizations do not provide admin accounts with write permission to the root C:\ directory. The install kits of most PI products copy the setup.ini to C:\pisetup.ini, and then write the logs to C:\ before moving them to %pipc%\dat, both of which require write permission to C:. The only workaround for now is to find someone with that permission to run the kit (typically an IT member).

Thanks for the info I'm facing this same issue. (BTW I do not have access to Osisoft Azure DevOps, please keep posting the status of the work item)

Are you asking specifically about the PI Server install kit?

Another option (suggested by Martin Bryant) would be able to specify the log path with a command line option or by editing the setup.ini file.

Agree with this concept. Instead of C:\ the installer should utilize %TEMP% or %TMP% for the pisetup.ini file and logs, before moving them to %PIHOME%\dat
