We have some accounts still running apps from 12.6 - which has been stable for many years - now suddenly we are sometimes seeing strange dw errors as below
Faulting application name: irights7.exe, version: 7.3.0.1, time stamp: 0x591962bf
Faulting module name: pbdwe126.dll, version: 12.6.0.3506, time stamp: 0x53bcd172
Exception code: 0xc000041d
Fault offset: 0x00000000000dd213
Faulting process id: 0x6958
Any ideas as to what could suddenly cause this?
