CST - CST 2024 shows a memory related warning after upgrading to Windows 11 version 24H2

Dear CST team,

 

My computer has upgraded to the newest version of Windows 11 (26100.2033) and I found that after starting any CST simulation, it always comes to an warning:

 

`tbbmalloc_proxy` cannot replace memory allocation routines (status:-1):
Success: free (ucrtbase.dll), byte pattern: 
Fail: _msize (ucrtbase.dll), byte pattern: 
The solver will continue with a reduced performance.

 

It is also noticed that the memory allocation for HF solver is abnormal, leading to slower calculation. Does CST software has compatibility issue with new Windows version? As Microsoft has started pushing this upgrade, can you have a check if it is a widespread problem?

Thank you for your support.

Regards,

Xu
