I have an old VB.Net application using Interop.ebCryptLib.dll that I couldn't get to work. I get the following error:
Retrieving COM class factory for component with CLSID {...} failed due to the following error: 80040154
I've searched for the error online and tried the following:
Register the dll using regsvr32 but I get the error "entry point was not found"
I tried recompiling the project and set the platform to x86 but still get the same error.
Is there any other suggestion I can try? This is an old application developed by another person. I do have access to the code and am unable to get it to work properly.
Was able to resolve this by finding the original ebCrypt.dll online. Thanks for the help #HansPassant

this exe comes along with 4 dll files in its own folder:
ATTPRV32.dll
Csta32.dll
Interop.AXS_INPROCLib.dll
Microsoft.VisualBasic.PowerPacks.Vs.dll
I've tried to register each of these dll files but got the same error message:
.DLL was loaded, but the DllRegisterServer entry point was not found
It means the class: 4C2901D1-5354-11D4-A6F9-00508B4ACA2C isnt in the registry plain and simple.
