Conflict with Adaptive Insights OfficeConnect in Excel
Problem
think-cell and Adaptive Insights (now Workday Adaptive Planning) OfficeConnect are enabled concurrently in Excel. I seemingly randomly receive one of the following error messages and Excel crashes:
-
CRITICALWITHMSG library\ui\win\safesubclassimpl.cpp(409):
APIERR 1400 Invalid window handle.
-
CRITICAL library\ui\win\safesubclassimpl.cpp(239): _ASSERT(0!=lResult)
Cause
Our developers analyzed the issue in detail. According to our analysis, hooking/unhooking issues cause this problem when multiple add-ins are available.
Solution
It is not possible for think-cell to work around this problem. We were already in contact with the Adaptive Insights / Workday Adaptive Planning support team. A solution is not yet available. If you want to ask for a fix, you may contact your Workday Adaptive Planning support and refer to help desk request: #208737: OfficeConnect Add-in compatibility issue with think-cell.
Workaround
To avoid the error from occurring, temporarily deactivate OfficeConnect or think-cell to be able to work with the other add-in.
