The following suggestions are based on very recent experience installing XPP 184.108.40.206 on Windows Server 2019
RE: Temporary Files Directory (PDF page 8 / 60 in instwin.pdf)
The XPP installation sets the temporary directory path to C:\Windows\Temp. The documentation points out that this folder is not always writable.
Can the out-of-the-box installation set the XYV_TMPS folder to one of the folders installation creates as part of the install (or the path used for either xz or sd_liz)?
RE: Windows OS Package (PDF page 7 / 60 in instwin.pdf)
A pre-installation check that performs the following would be a nice addition:
- check for the presence of the C++ 2017 Redistributable package and alert the installer if it's not found.
- verify that the three UAC settings are set properly:
- User Account Control slider bar.
- local security policy
(User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Mode) and
- registry entry
