Hello betaarchive.

I was installing the floppy version of Windows NT 3.1.
The installation failed after file copy.
It said:
Windows cannot install on this processor.
Setup cannot continue.

I am using AMD Athlon XP on 1.66 GHz.

Any help is very thankful.

can you at least search it on Google?
Anyways, after the text-based installation, open up the VHD or use MS-DOS with edit.com in it and edit the following lines of the following files:

from:
[ProcessorVar] STF_PROCESSOR = "" ? $(!LIBHANDLE) GetProcessor

to:
[ProcessorVar] STF_PROCESSOR = $(ProcessorID_I586)

on both setup.inf and initial.inf in the system32 folder.

Note: this also applies for Windows NT 3.5 and 3.51 Build 944

@TheCollector1988, you could at least be friendly to the new members.

Anyway.
What TheCollector1998 typed is correct, but that is only part of it.
I have found a nice tutorial on my favorite information site.

If you follow it, all of your installs are done smoothly and fast.

Most new people here should know how to partition and format a drive, that is why I didn't include that part of the tutorial.

I would consider that mostly their own fault, as they fail to use common sense as well as search engines...

Remember, though, that not everyone is from the First World West (the United States, Canada, Western Europe, Australia, and New Zealand), or even places of which are closely tied with that part of the world as you might be, and that as such, although English is still largely the sole universal language of the world, there are people from other parts of the world of whom may have trouble speaking it, and as such, may not even know thw words for certain things, including technology-related items.

As such, they may not feel comfortable (at least not at first) with even doing Google searches (or searches using other search engines, mostly if not almost certainly similar ones), or even what others would normally regard as "common sense". It's also possible that they are actually trying to do such, yet cannot even get their points accross to us.

Also, how would you like it, if you were new to something, and someone else acted as if understanding it should have been taken for granted. No offence to anyone at all, I'm just asking.

To answer your question: I would first look into it before posting/speaking/etc...

What emulator are you using, VPC2007, VmWare, etc? That system sounds way too new to run it natively.

Don't forget ncpashel.inf.

that file isn't required to be fixed

Thanks for help. I use VPC2004.

Always better to do a whole job than a half-arsed job.

qemu can handle the installation natively without any modification. It is compiled with quite a few types of CPU, from 486 to Pentium3 and Core 2 Duo, even with CPUs of other archetectures.
In addition, it is possible to modify those two files in installation CD or floppy image (compressed with cab), and then there will no longer errors during installation.

Now i realize that i need the PII patch as NT 3.1 and 3.5 won't install without modifying and that was fixed in 3.51.
