Try installing it in compatibility mode with any of the mentioned required OSes (XP or Vista).

i don’t have Compatibility mode because compatibility mode is missing. how do i enable that?

Give this a try:
https://www.sevenforums.com/tutorials/237405-compatibility-tab-add-remove-properties.html
(scroll until you see “To add Compatibility tab to Properties”)
Let me know (after trying) if it brought back the compatibility tab or not.

follow the mods instructions and get compatibility mode and if that dosent work you most likley cant run it or you can try to find the values for supported oses and try to change them. on an unrelated note if you have the artchived offline installer for windows onecare could you please share it because its very rare and i havent found a copy that works yet

6

There’s another way: launch the Program Compatibility Troubleshooter.

7

2nd and most huge problem: the servers for the program are dead

EDIT: i found out about Onecare rewritten so… check it out! https://onecare.cloudlillith.net

Hi,

If you’re still after OneCare Rewritten, the project will allow you to install it on Vista and Vista 64-Bit.

The packages provided aren’t compatible with anything past 7 as far as I’ve tried, the MSI’s fail with a tonne of errors. Perhaps I’ll look into fixing it in future, but the likelihood of it working is slim as Windows 10/11’s defender won’t be aware of OneCare and may potentially clash, especially if they use the same files to store definitions, it’ll most likely break one or the other.

I’ll have a look but no promises, OneCare Rewritten is to allow you to install it on Vista with possible XP support in future, anything newer simply won’t work.

Thanks,
Dan

He was just writing a status update for his project, no need to make fun :confused:

Doesn’t bother me in all honesty. I only came to this page after I was pinged about it in discord earlier today. The project was a one-off to help MJD. I literally have no use for it and realistically others shouldn’t be using it considering it’s ancient software for OSes that no longer have any support.
