Thank you for the post.
FileMaker's Technical Support does not charge for installation issues, so if you would like over the phone assistance with the installation and are located in the U.S. or Canada, then contact technical support toll free at 1-800-325-2747. The hours are between 7 AM - 5 PM PDT.
If you are located outside of North America, then locate the technical support office nearest you from the following link:
My suggestions for troubleshooting follow:
1. Redownload the full FileMaker Server 13.0v2 installer from your store email
2. Uninstall the following:
FileMaker Server 13
IIS URL Rewrite Module
Microsoft Application Request Routing
Microsoft External Cache for IIS
Microsoft Visual C++ 2012 Redistributable Package (x64)
Microsoft Web Farm Framework
3. Reinstall with the full FileMaker Server 13.0v2 installer.
The above steps will reinstall all of those components; however, if the above does not resolve the issue, please let me know and we can discuss next steps.
