Installation problem

[TizMe]

V8.0.6 / 8.0.9 / 9.0.x

All problem installation!

When launching the installation it stops and says that I must have at least Windows 8.1!
The PC has Windosw 10 updated!
Is it necessary to uninstall version 8.0.2 before installing 9…x.x?
Is that the problem?

Thanks.

Nope . . . . . . . . .

The installer is a NSIS installer and uses NSIS Windows version detection.

  !ifdef MSVC
  ; MSVC builds use python 3.8+ which dropped windows 7 support and will crash
  ${IfNot} ${AtLeastWin8.1}
      MessageBox MB_OK|MB_TOPMOST $(ERROR_WIN_MIN)
      Quit
  ${EndIf}
  !endif

For some reason that fails on your platform. NSIS “AtLeastWin8.1” does some checks on the system to find out its version. Is there anything special in your Windows installation?

@marekr can you perhaps say something about this?

[TizMe]

Nothing special a W10 version installed on the virtual machine in Parallel 18 on MacOS Catalina 10.15.

Can you run cmd and post the version shown in the first line?
