I got a file.rodl but when I try to regenerate the source code I receive a error “OLE error 80131040, ClassID: {F94EEEBC-9966-4B32-9C9C-763B22E31B20}”.
Our version is 10.0.0.1495.
The error happen by Delphi or ROServiceBuilder.exe

Hmm, this sounds like a faulty installation/registry configuration for a COM component. Can you try reinstalling? Alternatively, does the `rodl2code.exe` command line tool work, as a workaround? it uses .NET, so it doesn’t need to go thru COM for this, as the Delphi-based tools do…

Hi,
have you uninstalled any of our products like Remoting SDK for .NET, etc recently?
pls launch
```auto
C:\Windows\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe "C:\Program Files (x86)\RemObjects Software\RemObjects SDK (Common)\Bin\RemObjects.DataAbstract.CodeGen4.dll"
```
with administrative rights. it should solve this case.

It worked perfectly, thank you very much.
