Rollback manager for Affinity Photo and Photoshop

The moment this becomes urgent: a studio's senior retoucher updates Photoshop, a critical plugin stops working, and the team can't find the old installer. Adobe's Creative Cloud doesn't make it easy to go back — the 'Previous Version' option in the Creative Cloud app is buried, frequently broken, and only retains one prior version. Affinity's one-time purchase model makes this even harder because there's no official rollback path at all if you updated through the Mac App Store.

The gap exists because both vendors treat older versions as liability, not value. Adobe's Creative Cloud is designed to move users forward, and keeping old installers accessible competes with their narrative that every update is an improvement. Affinity (Serif) routes updates through the Mac App Store, which gives them no mechanism to offer rollbacks even if they wanted to. Neither vendor has a reason to make reverting easy — it would implicitly acknowledge that updates are sometimes worse than what they replaced.

Users describe needing to roll back 'to avoid glaring bugs that take time to be resolved' and mention that doing so is non-trivial enough to be a real complaint. What's actually missing is a managed archive of previous installers — verified, version-specific, matched to OS version — combined with a clean uninstall/reinstall sequence that doesn't leave behind conflicting preference fragments from the newer version. The specific failure mode users hit is that even when they find an old installer, the new version has left behind registry entries or preference files that cause the old version to behave unexpectedly.

This is a business because the rollback need is time-sensitive — when a studio's workflow is broken, they need to be back in 20 minutes, not two hours of forum-hunting — and because the need recurs with every major release cycle. A retouching business that bills $5,000 a week can't absorb a half-day of downtime.

What to build

Build a desktop utility that maintains a local archive of the last three installer versions for Photoshop and Affinity Photo, performs a clean version switch (uninstall current, purge version-specific preference conflicts, reinstall selected version) in one operation, and restores the preference snapshot corresponding to the selected version.

Where to start

Launch with Affinity Photo first, targeting users who bought the perpetual license specifically to avoid subscription pressure — these users are already predisposed to owning their tools, more likely to install a local utility that gives them control, and Affinity's Mac App Store delivery means their rollback problem is completely unsolved by any official mechanism.

The hard part

Sourcing and legally hosting verified historical installers for Photoshop is genuinely difficult — Adobe's terms of service restrict redistribution, so the product may need to guide users to cache their own installers at install time rather than pulling from a central repository, which means users who didn't install the agent before updating are already stuck.

How it makes money

One-time purchase at $29 per machine, with an optional $9/year maintenance subscription for continued version database updates as new app versions are released.
