Vkontakte open api and rights issue?

Question

JavaScript

I can not figure out how to set the rights to the application. Everything seems to be simple:
We connect in the header

&lt;script src=&quot;http://vk.antizapret.ru/js/api/xd_connection.js?2&quot; type=&quot;text/javascript&quot;&gt;&lt;/script&gt;<br/>
&lt;script src=&quot;http://vkontakte.ru/js/api/openapi.js&quot; type=&quot;text/javascript&quot;&gt;&lt;/script&gt;<br/>

Next, write in body

&lt;script type=&quot;text/javascript&quot;&gt;<br/>
<br/>
VK.init({<br/>
 apiId: my_id<br/>
 });<br/>
<br/>
VK.UI.button('login_button');<br/>
<br/>
VK.callMethod('showInstallBox',0);<br/>
&lt;/script&gt;<br/>
<br/>

Authorization is normal, all api through VK.api are working fine, but as soon as I want to call showInstallBox an error appears

TypeError: Result of expression 'options' [undefined] is not an object. vkontakte.ru/js/api/openapi.js:317

I also tried to call on onClick, after the page is fully loaded, the same thing.
What am I doing wrong? Maybe something is not connected? Maybe I'm calling it wrong?
Thank you in advance.

Similar problem.
I figured out what is happening because of the conflict between xd_connection and openapi.
If xd_connection is loaded first, then the openapi functions (widgets, etc.) do not work, if vice versa, then the js api functionality of the contact does not work accordingly.
