## Key points

- An installer update disabled other software on more than 600 PCs.
- The vendor replaced the affected machines.
- Faulty CDs and packaging worth $1 million were scrapped.

## Summary

A developer’s decision to force Windows registry updates in an accounting software installer left more than 600 customers with PCs on which other software no longer worked. The company replaced the machines and later withdrew the faulty software, turning an attempt to improve installation success into a costly failure.

The incident happened when the vendor was preparing its annual CD-ROM release for sale before a major holiday. Developers struggled to reproduce the fault until a customer provided a machine with a registry restore point; after investigating it, they produced a fix. The company then scrapped CDs and packaging valued at $1 million, while one engineer who collected the customer’s PC was invited to the holiday meal.
