DLSS 5 Swapper: Windows Will Not Let This App Write
"Windows will not let this app write to the game folder": the game is in a protected folder such as Program Files. Nothing was changed. Two fixes.
자주 묻는 질문
Did DLSS 5 Swapper change any of my game files?
Is it safe to run DLSS 5 Swapper as administrator?
Why do EA games show this message?
What does "Close the game and its helper processes" mean instead?
What does “Windows will not let this app write to the game folder” mean?
Windows blocked the install, and nothing was changed. DLSS 5 Swapper shows this message when it cannot write into the folder of the game you selected:
Windows will not let this app write to the game folder, so nothing was changed. Games installed under Program Files are protected: run DLSS 5 Swapper as administrator, or move the game to another folder.
Since v2.2.7, the app checks write access before it installs anything. Before that, the same problem appeared halfway through the install as EPERM: operation not permitted, when the app tried to create its backup folder _DLSS5_Backup (issue #301).
Why does it happen?
The usual cause is a game installed under C:\Program Files or C:\Program Files (x86). Windows protects these folders, so an app running with normal rights cannot create files in them.
In issue #301, Need for Speed Heat was installed in C:\Program Files\EA Games. The developer explained that EA installs games into Program Files, so the app could not create its backup folder there. The check comes first because the backup is the first thing the app writes (source).
How do I fix it?
Pick one of the two fixes the developer recommends:
- Run DLSS 5 Swapper as administrator for this install. Close the app, right-click it and choose Run as administrator, then install again. Give these rights only to the official build: check its SHA-256 first.
- Move the game out of Program Files, for example to
D:\Games. Use the launcher’s own move option, so the launcher still finds the game. Then install again from the new location.
Close the game before either fix. After the install, check that DLSS 5 is active. If the game already has other mods, back it up first, and use Restore originals to undo the install later (removal guide).
What if the message is different?
| Message | Meaning | Fix |
|---|---|---|
| Close the game and its helper processes before installing, switching or restoring. | The game or one of its helpers is still running | Close it completely, then install again |
EPERM: operation not permitted |
The same protected-folder problem, shown by versions before v2.2.7 | Update to the current release, or use one of the fixes above |
| Any other error | Another step failed | Find the failed step |
Save the exact message and the game’s path before you change anything. They tell you which of these cases you have.
