I have an old Windows app written around 2004. The app needs to create/read/write an XML file. If the app is installed in Win7 and then upgraded to all versions of Win10, it will work ok. However, if it is installed under Win10 21H1 and newer, it cannot create/read/write the XML file. I THINK it used to work ok if installed under Win10 2004.
So something was changed in the Win10 updates, but I don't know how to fix it.
I have tried changing the security ownership (read/write/delete) and Windows7 compatibility, but it didn't work.
Anyone has any idea as to how to fix this?
Thanks in advance.

If you debug the application, what specifically fails?
I don't have the source code to the app. But the error message is that it cannot create the xml file.
I can see similar error in the installation of Office 2007 where by it needs to open and read an xml file. The installation failed. It used to work in older Win10 version.
If it's not your application, have you reported it to the application's authors?
Other than that, have you tried running it as administrator?
yes, I have tried running it as administrator and win7 compatibility mode.
The author of the app is unknown. The app is from Kodak, which is out of business.
Have you searched for others with the same problem with that application? You're rarely alone with a problem!
Final suggestion... you could try using the SysInternals Process Monitor to log the file operations to identify the operation that fails and hope that information will give you some insight about what you might be able to alter to resolve the issue.
Thank you for recommending SysInternals Process Monitor . It turns out that the app was trying to create a folder in C:\program files\Common Files and win10 22h2 blocked it. I had to manually create the folder and grant the app the read/write rights to the folder and that solved the problem.
Good, I'm glad Process Monitor helped you identify the problem.
