Hello,
2
3I'm experiencing a critical issue where the UiPath Robot hangs and freezes all desktop applications (including SAP GUI, Excel, etc.) when running a workflow that uses Excel activities.
4
5The error appears in the Windows Event Log as:
UiPath.Executor 24.10.12.0
Duplicate assembly: E:\uipath\packages\uipath.officelibs\1.0.0\lib\net6.0-windows7.0/OFFICE.dll
Duplicate assembly: .../Microsoft.Office.Interop.Excel.dll
This happens consistently in **UiPath Studio 24.10.12** and **Robot 24.10.12**, even though I'm not directly using Excel in my Python script — only via UiPath's Excel.Activities package.
After upgrading to **24.10.13**, the issue seems to be resolved, but I want to confirm if this is a known bug and whether it has been officially fixed.
Could you please confirm:
1. Is this a known issue in 24.10.12?
2. Has it been fixed in 24.10.13 or later versions?
Thank you!
Thank you for the clarification.
However, in UiPath Studio/Robot v24.10.12, this “Duplicate assembly” error does cause the robot to hang completely, freezing SAP GUI, Excel, and all desktop applications — even though the process shows errorId=0.
After upgrading to v24.10.13, the same workflow runs successfully (only the log remains).
Could this indicate a regression or hidden bug in v24.10.12 that was fixed in later patches?
Check your dependencies and see which two dependencies have same packages and try to change the versions or match them
Mostly mail and excel packages are conflicting
Cheers
hi Anil_G
My dependency versions are as shown in the image above. Could they cause all desktop applications to become unresponsive during runtime?
THANKS!
Hi @DI.YANG
Yes, this is a known issue in UiPath 24.10.12 related to Excel/Office assemblies being loaded twice, which can cause the Robot to hang and freeze other desktop apps.
The issue has been fixed in 24.10.13, and upgrading resolves the problem.
