Just an update, if you are installing AutoCAD and the log file has the following error:
(SERVER) MSI (s) (9C:9C) [08:04:16:995]:
Invoking remote custom action. DLL: C:\Windows\Installer\MSI5A0.tmp,
(UNKNOWN) Action start 8:04:16:
(UNKNOWN) CustomAction StreamOutFNPCADLL
returned actual error code 1603
The solution is to set "TMP or "TEMP" environment varilable to point to a location that the installer has read/write access.
1. Create a folder at C:\temp and include "Everyone" with full permissions.
2. Right Mouse click on Computer and select Properties > Advanced > Environment Variables.
3. Change the following values:
The default Value for TEMP and TMP is: %USERPROFILE%\AppData\Local\Temp
Thanks to Alison Gangler for this tip.
