Install and operate deliberately
- Preserve original media, service-pack files and component installers.
- Use a documented installation sequence and record any compatibility settings.
- Register design-time controls in the correct 32-bit context and verify licenses.
- Keep projects in writable, stable paths rather than protected system directories.
- Use elevation only for tasks that require it; test built applications as normal users.
- Verify debugger behavior, API calls, database providers and external tools.
Opening a project with unavailable controls can replace or lose form metadata. Work on copies until every reference and component resolves.
Know when isolation is safer
| Host installation | Convenient when dependencies are understood and do not weaken the workstation. |
|---|---|
| Virtual machine | Useful for pinned components, old SDKs or conflicting registrations. |
| Preserved original image | Essential evidence when licensing or undocumented setup cannot be recreated. |

Start with environment recovery, assess the deployed target through modern Windows migration, package outputs through installer modernization and use the VB6 pillar.
