WDC TIDE rabbit hole

[BC238C]

After some month of tinkering with the 6502 I decided to buy a WDC W65C02SXB board. However, I am very confused regarding the TIDE IDE. So here are some questions I have:

1)
I used the youtube tutorial from WDC to do a first approach, copied a file and deleted the additional settings file as described. The following error occured:
!CreateProcess: Unable to Start Application
What application? The assembler? I let all directory settings as default.

2)
After deciding to sleep on it the next day the code assembled. However, I get a shipload of errors for code like:
File_108= VIA_ORB: equ VIA_BASE.c
File_109= VIA_IRB: equ VIA_BASE.c
What is the idea of having all lines of code ending with ".c" in an .asm file? Do I need to write code in the same syntax style?

3)
How to deal with the debugger? The built-in help in the debugger leads me to an Microsoft end-of-support website. What?!?

4)
All that weird behaviour and frustration brings me to the idea to simply use the debugger as a command-line to to upload code to the board. But as I said: No chance to RTFM. Do I have to buy a WinXP machine then...?

Welcome! I can't help directly, but I see TIDE is mentioned in previous threads (not always in a good way)

WDC Tools gotcha's
WDC Terbium IDE (Tide) with the W65C816
OSI Basic won't parse commands - syntax error
WDC02CC Compiler
WDC Tools STARTUP.ASM and C samples files for 6502/816
W65C02SXB board

There's more but I'll stop there. Hopefully that, or someone here, can help.

Thanks, I'll test it.
The concept of that IDE is really of a peculiar one... but little by little the fog clears...
