How to grant folder permissions?

Question

I'm creating an MSI installer using Wix Toolset and writing several files to Program Data. However, after installation, the program, even if it's not running as administrator, can't write to these files. How can I fix this?

Use CreateFolder with a PermissionEx element under it.

Solved by using wix toolset utils extension

<xmlns:utils="http://wixtoolset.org/schemas/v4/wxs/util>
<CreateFolder Directory="ID">
   <utils:PermissionEx GenericAll="yes" User="Users" ChangePermission="yes"/>
</CreateFolder>
