Rosetta 2 - Build 1.0.0.0.1.1744447383

Goal: Manually install an explicit version of Rosetta2

Background: Me and some customers have an old app (intel) which perfectly worked with Rosetta2. In the last week of April most macheines were updated to Mac Os 15.4.1. and the app still starts but certain functionality is bronken. Some fields ind the forms don't write back to the database, some data can't be read from the database. (Most installations will fade out over the next month but it would be great to have the app fully working for data migration.)

First try was to step back to 15.4. (Clean Install - Install App - Rosetta installs as expected): no change, app still broken

Second try back to 15: (Clean Install - Install App - Rosetta installs as expected): App still broken (!) This is interesting as the app worked for month using Mac Os 15!

Third try: Back to MacOS 14 (Clean Install - Install App - Rosetta installs as expected): App is working like nothing happend.

(All attempts on same hardware of course.)

Reasoning: Rosetta2 was the only software (besides the app itself) installed after clean MacOS installs. Now, my guess is that there were might be a change in Rosetta2 as the app worked on MacOs 15 up the update 15.4.1. was installed.

Checking versions (pkgutil --pkg-info com.apple.pkg.RosettaUpdateAuto): Rosetta version MacOS 14: 1.0.0.0.1.1722778371 Rosetta version on MacOS 15.4.1: 1.0.0.0.1.1744447383

To fully verify the cause it would be great to uninstall Rosetta on MacOS15.4.1 machine and explicit install lower version (1.0.0.0.1.1722778371) which must be available somewhere as MacOS14 still gets this version.

I know how to uninstall - is there a possibility to manually install an explicit version of Rosetta2?
