回答1:
ACL Permissioning: Adding write permissions for regular users is usually considered an anti-pattern, but sometimes you need to share a file among all users of the PC for pragmatic purposes.
Write Access: For the record: Here is a list of approaches to deal with permission denied issues. Most of the options listed are not good at all - and that is why the list was made - we need to remember why they are bad and what alternatives exist.
Deployment Tool: Application of custom ACL permissioning - to open a file in a protected disk location for writing by all users - is different depending on what tool you use to make your MSI. Since you don't specify WiX, Installshield, Advanced Installer or something else I am not sure how to answer. Let me use links instead:
WiX:
- Different WiX permission elements - there are two different PermissionEx elements (!)
- PermissionEx (Util Extension - WiX's own stuff)
- Util Version: Wix: How to set permissions for folder and all sub folders
- PermissionEx (MSI5 only - uses the built in
MsiLockPermissionsExTable)- MSI5 Version: How to deny folder permission to Users with wix installer
- PermissionEx (Util Extension - WiX's own stuff)
- There are two more (do not use):
- Permission (legacy MSI LockPermission table)
- FileSharePermission (for share permissioning - use when you need share permissioning)
Installshield:
- Configuring Permissions for Files and Folders
- Setting Permissions in Windows Installer: MSILockPermissionsEX and ISLockPermissions
- Installshield Folder Permissions not working
Advanced Installer:
- Apply permissions by right clicking a folder and going to properties: Permission Dialog.
- It seems this uses the old, legacy
LockPermission table.
There are some other tools as described here: Short List. Secondary (more links).
