Hi,   We are currently attempting to update our installshield projects to Installshield 2019. We have one which installs our software's webservices which is working fine in 2016. However when we try to build it in 2019 we are getting the following errors Error RC2170 : bitmap file <Path>\DetectIIS6Compat.dll is not in 3.00 format Error -6118: The Resource compiler failed to build the RES file "<Path>\ProteanWebServices74\_ISUser_0x0409.res" required to link the DLL.   I have tracked it down to a custom action for detecting IIS6 compatibility using DetectIIS6Compat.dll as described in this article  https://helpnet.flexerasoftware.com/installshield22helplib/helplibrary/IISMetabaseCompat.htm   As far as I am aware this is a dll that is included within Installshield. Anyone have  ideas on how to solve this?  Any help would be gratefully received Thanks   Simon ... View more
