Recently Microsoft considerably changed their bing Translator service. Currently, bing Translator is a paid service – however a free version is still available and described below.
To use this service an account on Microsoft Azure website is required, and you need to register an API client id. Unfortunately, this process is complicated, because Microsoft sited have lot of menus, pages and forms, so users could mix up some steps or codes. Luckily, our R&D implemented very helpful links to changed Microsoft Translator API, available via “Get account” button and “Register account” buttons:

Below is a short guide, how to register bing Translator in your copy of Sisulizer:
When you click on “Get account” button in “Tools” menu -> “Translation Engines” -> “MS Translator”, Sisulizer will open Microsoft Azure Marketplace website in your default Internet browser. Here you can select most appropriated plan. At the bottom of the list with available paid options, you can find freware subscription plan for MS Translator. It allows you translate 2000 000 characters per month via registered API, and when month ends, counter is rested. I think this is still very good option, especially because Google doesn’t offer freeware version of their auto-translation service.

When you selected most appropriated option for you, click on “SIGN UP” button in bottom right corner of selected option. If you aren’t logged on your MS account, it should redirect you on Microsoft login website. After login, you’ll see checkout confirmation page. If you haven’t had account on Microsoft website yet, you could create your account by click “Sign up now” link in bottom part of login site.
When you finished subscription process, you can connect your subscription with API in your Sisulizer copy. Click “Register account” button in “Tools” menu -> “Translation Engines” -> “MS Translator”. This opens Applications site on your Microsoft account (if you aren’t logged to your account, you will be first redirected on login page) where you should click “Register” button. It opens form with automatically generated Client secret key.

Fill Client ID and all other required fields and click “Create” button. When you back on “Applications” site on your account, you’ll see new application entry in bottom part of site, with “Edit” and “Delete” links. Via “Edit” link you can later get access to your Client secret – for example, you could copy it and paste to your application.
Now, you can back to Sisulizer and paste Client ID and Client Secret keys to appropriated fields, like on below screenshot.

After this, I recommend you click “Test” button. From build 335, this feature perform real connection test with MS service, and when you have empty Client ID and secret fields, you’ll see this message:

When your data are incorrect, you’ll see this message:

When your Client ID and secret are matched with your account data, you’ll see this message:

Of course, for performing this test (and for using MS Translator) required is Internet connection. Because Sisulizer connects with external server during test, so it take some time, so be patient.
Notes
Your Microsoft could contains different keys, that is main account key, keys for other applications and services, client IDs, etc. and it could mislead user, so you need be careful and type/paste right keys to Sisulizer. For example, on below screenshot are indicated account keys, but they aren’t MS Translator API’s keys. However, I hope links available via Sisulizer GUI and this short guide help you correctly register your MS Translator service.

Data form above screenshots were made with test account, created only for this article and you should use your own data during registration.
