I have an application (C#) which uses ComInterop with CorelDraw x8
After Updating to Windows 1607 (Anniversary Update), things stop working immediately with creating my object (cdr = new CorelDRAW.Application();), or with the next line (hiding CorelDraw's window) with an error:
cdr = new CorelDRAW.Application();
System.Runtime.InteropServices.COMException App busy. (Ausnahme von HRESULT: 0x8001010A (RPC_E_SERVERCALL_RETRYLATER))
System.Runtime.InteropServices.COMException
App busy.
(Ausnahme von HRESULT: 0x8001010A (RPC_E_SERVERCALL_RETRYLATER))
or later
HRESULT: 0x80010105 (RPC_E_SERVERFAULT)
Same app with same Version of CorelDraw x8 under Windows 7 continued working as it should, and after uninstalling Windows 10 Anniversary Update, my apps is working again as intended.
So, does anyone know how to work around this issue? Is it known yet? Any help welcome :) !
