I'm trying to installSQL Server 2012 Express (which is a dependency for my Net2 door access system).
The redistrubtioned version that comes with the Net2 installer fails, so I thought I'd try and install it manually first.
I'e downloaded it from: https://www.microsoft.com/en-gb/download/confirmation.aspx?id=29062
I run it and it unpacks, a DOS type CMD screen briefly flashes, then the temp folder it unpacks to gets removed.
I've tried unpacking it manually uzing 7zip then running setup.exe a DOS type CMD screen briefly flashes, a DOS type CMD screen briefly flashes, then nothing.
I've also tried running as administrator and with the AV disabled.
This server did have SQL express on before for Veeam but I've uninstalled it and cleaned up any folders I can find.
Any ideas?
Thanks
