Hello everyone, I have a issue when we open ax client (Ax 2012 R3) its throw error APPCRASH. Please remeber its throw error before auc files creation. AUC file are not created so i’m not able to delete it.
Please give us more information - when it started happening, what has changed, whether it happens to all users and so on.
Then check event logs. They usually don’t reveal much, but you can at least find out what exception it was and in which file.
A more powerful approach is generating a memory dump on crash and analyzing it with WinDbg, which will also gives you the stack trace and other details. But it’s not exactly user friendly. 
Hello Martin… we check event viewer logs and found two error.
