Spectrus: CompassXtractMs.dll registration fails during installation

Description

During installation of Spectrus software, the setup failed with the message "Registering CompassXtractMs.dll... fail!". The failure was caused by missing or incompatible Microsoft Visual C++ Redistributable packages required by the Bruker/Compass filter components. Installing the appropriate C++ Redistributables and re-running the installer resolves the issue.

Solution

1. Verify Windows edition and version (Start > About your PC > Windows specifications) to ensure compatibility.
2. Check installed Microsoft Visual C++ Redistributables (Control Panel > Programs & Features).
3. Install required VC++ Redistributables (x86 and x64) commonly needed by the product and Bruker Compass components (e.g., 2008 SP1, 2010, 2012, 2013, 2015–2019/2022). Obtain packages from Microsoft’s official site.
4. Reboot after installing Redistributables (recommended).
5. Extract all installer files to the same folder and run SETUP.EXE as administrator (right-click and select Run as administrator).
6. During installation, deselect software update if advised by the package notes and proceed with registration per instructions.
7. Ensure antivirus or endpoint protection is not blocking DLL registration; temporarily allowing the installer and components if required.
8. Confirm that .NET Framework prerequisites (if any) are installed per product documentation.
9. Retry installation and confirm successful completion without CompassXtractMs.dll errors.
