What steps will reproduce the problem? 1. Install install_protege_4.1.exe on Windows Server 2008 R2 2. Launch 3. Everything fine until Fact++ which raises:

org.osgi.framework.BundleException: Unresolved constraint in bundle uk.ac.manchester.cs.owl.factplusplus [13]: No matching native libraries found.

What is the expected output? What do you see instead? Works fine on Windows 7.

What version of the product are you using? On what operating system? FaCTpp-win-v1.5.1

Please provide any additional information below.

Should be fixed in a fresh 1.5.2 release. Could you please try it and let me know whether it is working properly.

Hi Fact++ (Dmitry Tsarkov)

Thank-you for your response and I can confirm it runs just fine on Windows Server 2008 R2 64 bit.

Interestingly, this morning I uninstalled Protégé and downloaded the latest build and 1.5.1 worked! But, I waited for the very cool online update to kick in so I was able to confirm that 1.5.2 continues to work.
