Cannot Modify Core Units.cfg

[stegyre]

I'm stymied. In the past, on other BfW installations on other computers, I've been able to modify core files to customize my BfW. This time, this computer, "denied"!

BfW version is 1.12.5
Microsoft Windows 10 OS (should be fully up-to-date – I think it updates automatically these days)
Specific file I'm working on: core/units.cfg
App used for making the edits: WordPad

Things already tried: I did check the files Properties, went under the Security tab, and enabled "Full control," which is supposed to enable modifications and writing to the file, as well as "Read" and "Read & execute" (which were the only two options originally enabled). (Note: for my level of computer savvy, this qualifies as "elite hacking.")

Any advice on what my problem may be?

(Edit: fwiw, the specific edit I am trying to make is to add {TRAIT_HEALTHY} and {TRAIT_DEXTROUS} to the list of universal traits.)

If you installed your wesnoth to protected directory then you might need to open your editor as admin.

Yes!

It took a little poking around: my account already has admin privileges, so that wasn't it. Choosing to run WordPad as administrator, however, solved the problem.

Thanks for the assist.

I like that minimalist approach!

But I agree that Notepad++ is great.
