xlloop addin / opuxl config

[alexacomputing]

I am trying to setup the alexacomputing.com webpage that uses xlloop or similar addin (opuxl) to perform excel computations. To do so I need to resolve the following issues

1. Currently only 32-bit xlloop and opuxl are recognized by excel as proper addins. I have 64-bit windows 10 machine and 32-bit excel app. Both 64-bit xlloop and opuxl are not recognized as addins. The problem with 32-bit xlloop addin is that it works only in the following sequence: start excel -> start java server. Otherwise excel freezes. As a result I can't run it with external server (only with localhost). 32-bit opuxl freezes excel all the time. I tried to rebuild the xlloop in vs15 (I am new to visual studio so I am likely missing something) but also can't make excel recognize it as addin.
2. Configure the opuxl addin same way as you configure xlloop for example to connect to external server (using .ini file). There is a sample config file in the distribution but I was wondering whether a config file with a detailed list of parameters exist.

Not sure why neither xlloop addin or config files are not part of the project. Any help will be highly appreciated
