Sometimes when you run OLI Flowsheet: ESP for the second time, you will receive the following error:
This error occurs because, during the installation of OLI Flowsheet: ESP, Microsoft Windows doesn't think it is compatible with Windows 10 or later. A flag is set in the registry to force compatibility. This is unnecessary because OLI Flowsheet is compatible with Windows 10. A DLL is not properly unloaded between calculations and thus causes the error.
There is a complicated fix for Versions 10, 11, and 12 of OLI Flowsheet: ESP.
- Download the attached zip file.
- Extract EXE files to a folder.
- You can then run the EXE file by double-clicking. If a compatibility flag error is found, you can now fix it.
