      <title>CUI JIT Crash</title>
      <link>https://forums.autodesk.com/t5/autocad-forum/cui-jit-crash/m-p/7113839#M225093</link>
      <description>&lt;P&gt;In ACAD 2017, every time I try to change the images for my custom commands the CUI editor gives me a non-fatal JIT crash. This mean I have to unzip my CUIX files and edit the text manually, which is a bit of a PITA. How can I fix this?&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;EM&gt;"Unhandled exception has occurred in a component in your application. If you click Continue, the application will ignore this error and attempt to continue.&lt;/EM&gt;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;EM&gt;Object reference not set to an instance of an object"&lt;/EM&gt;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;

      <description>&lt;P&gt;Hi,&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;EM&gt;&lt;FONT color="#000080"&gt;&amp;gt;&amp;gt; In ACAD 2017,&lt;/FONT&gt;&lt;/EM&gt;&lt;/P&gt;
&lt;P&gt;The first idea I have is to make sure your AutoCAD is up-to-date. Which version/update do you have installed (command &lt;STRONG&gt;&lt;FONT color="#000080"&gt;_ABOUT&lt;/FONT&gt;&lt;/STRONG&gt; shows it)&lt;/P&gt;
&lt;P&gt;Another idea is to verify if the CUI can be handled at other workstations (or when you start AutoCAD with a new Windows user account).&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;

      <description>&lt;P&gt;I'm using version N.104.0.0 AutoCAD 2017 SP1.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;The CUI file works OK, it seems to be the editor that doesn't - I can't change any&amp;nbsp;images.&lt;/P&gt;</description>

      <description>&lt;P&gt;I'm still getting this in AutoCAD 2018 - does no one from AutoDesk have any idea why this happens? I've seen several similar problems on the forums with no real solutions...&lt;/P&gt;</description>

      <description>&lt;P&gt;Hi,&lt;/P&gt;

&lt;P&gt;Sounds like you are using something again in 2018 what you used in 2017 ... did you migrate settings? Did you load your own CUI's?&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;EM&gt;&lt;FONT color="#000080"&gt;&amp;gt;&amp;gt; I've seen several similar problems on the forums with no real solutions...&lt;/FONT&gt;&lt;/EM&gt;&lt;/P&gt;
&lt;P&gt;Where?&lt;/P&gt;

      <description>&lt;P&gt;Thanks Alfred - that has actually put me on the right track! If I unload my partial CUIX I can change the icons. But when I load my file, I can't. So obviously, it is something in my file - but how do I find out what? As far as I can tell, everything else is working fine (i.e., all my commands work)&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I guess I was hoping that, knowing this happens immediately after I click an icon in the CUI icon grid for a command, and given this stack trace:&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;PRE&gt;System.NullReferenceException: Object reference not set to an instance of an object.

&lt;/PRE&gt;&lt;P&gt;I was hoping someone at AutoDesk might be able to give me some pointers....&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I wonder if it makes a difference that &lt;EM&gt;MY&lt;/EM&gt; icons are in a resource DLL?&lt;/P&gt;</description>

&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;EM&gt;&lt;FONT color="#000080"&gt;&amp;gt;&amp;gt; But when I load my file, I can't. So obviously, it is something in&lt;/FONT&gt;&lt;/EM&gt;&lt;/P&gt;

&lt;P&gt;Create a new CUIX and use the transfer option to move parts of your menu from the old file to the new file and see when the new file stops working.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;EM&gt;&lt;FONT color="#000080"&gt;&amp;gt;&amp;gt; I was hoping someone at AutoDesk might be able to give me some pointers....&lt;/FONT&gt;&lt;/EM&gt;&lt;/P&gt;
&lt;P&gt;Sorry that I'm not from Autodesk, but also they might need the CUIX, just guessing what is wrong with your file wihout seeing it is impossible.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;EM&gt;&lt;FONT color="#000080"&gt;&amp;gt;&amp;gt; I wonder if it makes a difference that MY icons are in a resource DLL?&lt;/FONT&gt;&lt;/EM&gt;&lt;/P&gt;
&lt;P&gt;Could be, if the DLL is defect or not found by AutoCAD.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;

      <description>&lt;P&gt;Hmmm...good idea, but I get the same error when I try to move &lt;EM&gt;anything&lt;/EM&gt; to a new CUIX using the Transfer tab...&lt;/P&gt;</description>

      <description>&lt;P&gt;With a hint from the stack trace and comparing with the contents of a new CUIX file I found that most of my entries in the internal CUI files were missing the &amp;lt;ModifiedRev&amp;gt; tag.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;AutoDesk people take note please! Just add it if it's missing, no need for an exception &lt;span class="lia-unicode-emoji" title=":winking_face:"&gt;😉&lt;/span&gt;&lt;/P&gt;</description>

      <description>&lt;P&gt;Just to point a out to AutoDesk - this is still a problem with legacy CUI files in AutoCAD 2020.&lt;/P&gt;</description>

      <description>&lt;P&gt;Still just as buggy in 2021&lt;/P&gt;&lt;P&gt;Never understand why AutoCAD can backup drawing files so well and have no method whatsoever for CUIX files.&lt;/P&gt;</description>
