Can't install Oscar.

[Mardymar]

I am getting "The Setup files are corrupted. Please obtain a new Copy of the program" error.
I'm not sure how to fix this.

Download a new copy of OSCAR and then scroll down to "Documents" and compare the file SHA256 checksum to the value in the checksum file. If they match, you're good to install.

Here is the link to the checksum file: https://www.apneaboard.com/OSCAR/OSCAR-1...cksums.txt

I solved my problem.  I am now able to run OSCAR again.  I don't know if it'll help anyone else with Windows 11 who is reading this thread, but here is what I did to resolve my problem.

1. I uninstalled OSCAR
2. I deleted C:/Users/John/Documents/OSCAR_Data using File Explorer
3. I created C:/Users/John/Documents/OSCAR_Data using File Explorer
4. Reinstall OSCAR

My hypothesis is that when OSCAR creates the directory, I wind up with different permissions compared to when I create the directory myself.

My other idea for people to try would be to temporarily turn off "Controlled folder access" in the "Ransomware protection" dialog of "Windows Security".  I don't know if this will help anyone or not, but thought I would suggest it because I just downloaded another open-source program called "Sweet Home 3D" and it doesn't let me save my designs unless I have "Controlled folder access" turned off.

I should have mentioned that I first tried uninstalling OSCAR and then re-installing it.  That didn't work.  So that's when I performed the process that I outlined above.

The OSCAR program is installed in a different location than the data. Uninstalling the program will not have any effect as to the read-write access capability of the data's location.
