  • You need to check the configuration file on the client.  This is caused by a number of things, but it usually concerns these settings.  I'd see if ithe client was pointed at the right server first.  

    Go to  Start > Control Panel > Administrative Tools > Microsoft Dynamics AX 2012 Configuration, and start comparing settings to users with working accounts. You'll probably find something.

  • Try clearing usage data and deleting user cache

  • Tim,

    Thank you for that suggestion. Clearing out the .auc file from the users profile fixed the problem.

  • How do you do this?   "Try clearing usage data and deleting user cache"  (AX32 is on a citrix server)  other users are not having this issue....Thanks in advance....

  • Usage data is held within AX.

    Login as the user. Go to File > Tools > Options > Usage data and click the Reset button to delete all usage data. Then log off and log back in.

    Clearing the cache is a bit tricker, becuase where it is depends a bit on the operating system. You're looking for files with a .auc extension and they're probably in something like C:\Users\xxxx\AppData\Local

  • Is there any option to clear this cache automatically? I have more than 10 users that same symptom, and I always clear it each of them every month. Thanks.

  • What version of AX?

    We have just gone live on AX 2012 R2 CU6. There were a lot of client crashes caused by End user form personalisation. We cleared the 'Form pre-loading enabled' option at System administration > Setup > System > Client performance options and that solved the issue, but I have heard that  the underlying issue is fixed in CU7.

  • Tim,  we  are running AX2012 R2 with no cumulative update (version, and yes we  have a lot of user  forms customized.

    This error shows only in branch office with Citrix XenApp, users in HQ never get this error.

    I am gonna try as you said Tim, let's see next month.


  • This solved my problem I cleared usage data and the error is gone. Thanks TIM

  • Thanks for the information.

    It also works to me.
