Hello $all,

I'm installing OS server version 8.1.3 x64 on a Windows server 2008R2/ 64bit -- using Omnis-App-Server-8.1.3-x64.exe installer file.
I have used this installer on the same version of windows more than 20 times so far with no issues. This time I'm getting an error when I try to run the installer (run as admin), the error says something like" error in copying files from packaged archive <path to the installer>  to C:\Users\DBSUPP~1.FI\AppData\Local\Temp\OS8.1.3SVR\Omnis-App-Server-8.1.3-Launcher-x64.exe..I have to click abort to the process to stop this error msg.

When I go to "C:\Users\DBSUPP~1.FI\AppData\Local\Temp" I see a file created called " bitrock_installer.txt", which has these log records:

My question, what makes this installer think that I need to run it in "mode win32"?
Anyone has seen this error before?

Thank you,
