The Invantive products execute a number of checks at application start to ensure that the environment running the software meets a number of pre-conditions as established by Invantive. These checks can be disabled for analysis purposes and out-of-the-ordinary deployment scenarios. ## All Platforms The following environment variables control startup checks and are available on all platforms and products: - `INVANTIVE_MIN_GB_FREE_SYSTEM`: minimum amount of free disk space in GB on the system disk during start up. Defaults to 5 GB. ## Microsoft Windows The following environment variables control OS platform and are available only on Microsoft Windows: - `INVANTIVE_CHECK_SYSTEM_COMPATIBILITY`: validate system compatibility. - `INVANTIVE_MAINTAIN_VSTO`: re-activate Invantive VSTO add-ins when disabled.
