macOS Sierra to High Sierra (unable)

I've tried numerous times (including with higher level apple support persons on the phone) to upgrade Sierra to High Sierra. I can download it but will not install in either regular or safe mode. "An error occurred while preparing the installation. Try running the application again".

10.13.6 no go, it wants 10.13 which is unfindable.

I tried 10.13.2. no go, it too wants 10.13

Tried terminal install process, no go..

macbook late 2009.

time to toss it into the recycle pile unless anyone out there has some magic......

thanks]

MacBook, macOS 10.13

Hi there,

I think you downloaded the 10.13.6 Combo Update which requires an earlier version of 10.13, use these instructions...

Don't use Firefox for this link...

If you get a corrupted message...

Naw, not damaged, it's just that you have an old copy already in Applications, TDon't use Firefox for this link...

Naw, not damaged, it's just that you have an old copy already in Applications, Trash the Install MacsOS High Sierra.app in Applications then a new copy more recent version can be downloaded.
