Hello, I have access to Fico Blaze Advisor but didn't find installation file. How to install?

It is unclear to me whether you mean you are lacking the installation instructions or the exe file that does the install. If you don't have the blaze-advisor_7.x.v#_Windows.exe file, you will not be able to install Blaze Advisor properly, and you should reach out to support to get access to the install file. If you have that file, and ran it and are trying to figure out what to do next, you would need to install Eclipse and then go through the process of installing Blaze Advisor as a plug in, going to Help > Install New Software, add a site, Local, where you installed the Blaze Advisor kit, and that will get it installed for you. The first installation step will also create a directory that has contains a doc directory, which will have a PDF directory, with the Installation instructions within it.
