# iNGs_Geo integration - availability and launch

Status: **published / evidence-aware integration knowledge**

## Optional dependency rule

iNGs_Geo is an **optional integration dependency** for MSet.

An MSet instruction or AI-generated workflow that uses an iNGs_Geo command must not assume that iNGs_Geo is installed, configured or currently loaded. Where availability matters, it should be confirmed by the user, detected by a supported mechanism, or treated as an explicit prerequisite.

The current evidence does **not** define a supported MSet-side detection API. Do not invent one.

## 64-bit installation orientation

The iNGs_Geo 11.70 manual documents a 64-bit installer named:

```text
iNGs_Geo_11.70_64_setup.exe
```

For the CONNECT/2023/2024 environments documented by that manual, installation typically provides configuration, application binaries and workspace/workset resources including `iNGs_Geo_CONNECT.cfg`, `iNGs_Geo.ma`, `iNGs_Geo.dll`, an `iNGs` workspace and an `iNGs_Geo` workset.

Exact physical paths depend on the Bentley product and environment. Do not hard-code a CONNECT-era path as a universal MicroStation 2025/2026 location without current evidence.

## Launch command

For the documented 64-bit Bentley environments, iNGs_Geo can be started from the MicroStation command line with:

```text
mdl load ings_geo
```

The manual also describes launching `iNGs_Geo.ma` from the MicroStation MDL Applications dialog. When the documented `iNGs` workspace and `iNGs_Geo` workset are selected, required resources can be made available and the application can also be launched from the iNGs ribbon.

## Autoload caution

The vendor manual explicitly says that starting iNGs_Geo together with MicroStation as a design-file application by setting `MS_DGNAPPS` is **not recommended**.

Therefore an MSet/iNGs_Geo workflow must not turn iNGs_Geo into an automatic `MS_DGNAPPS` dependency without a separate design decision and verification.

## MicroStation 2026 evidence

The 11.70 manual's written compatibility list ends at MicroStation 2024. On **2026-09-06**, PB (iNGs) confirmed to GRAPHICO that **iNGs_Geo 11.70 works with MicroStation 2026** and that he had not encountered a problem with that combination so far.

Classify this as **current vendor operational confirmation**. It does not mean that every individual key-in and parameter combination has been separately runtime-tested under MicroStation 2026.

## Unknown / do not infer

The current evidence does not establish:

- a supported MSet-side method for detecting whether iNGs_Geo is installed;
- a supported MSet-side method for detecting whether iNGs_Geo is already loaded;
- exact MicroStation 2025/2026 installation paths or configuration differences;
- explicit written MicroStation 2025 compatibility confirmation;
- exact failure text/behavior when an `ig_*` command is issued while iNGs_Geo is unavailable.
