I am using LibXL with DF 18.2 and classes from StarZen. Usually it works well, but by certain customers with computer networks there are problems.

When installing LibXL by customers, I put the files libxl.dll, libxl.net.dll and szLibXL.dll in the DF 18.2 bin folder.

Then the following commands are run from a .bat-file:

cd C:\Program Files (x86)\Dataflex 18.2\Bin
call C:\Windows\Microsoft.NET\Framework\v4.0.30319\RegA sm.exe szLibXL.dll /CODEBASE

This is done on every computer as well as on the server in networks.

By one customer, LibXL doesn’t work on any machine. They probably run Windows 10 on all terminals and Windows Server 2012. By another customer LibXL works on three computers with Window7 but not on two other with Windows 10.

The error messages are show already when the DF application is started.

Unable to instantiate COM object. Active X component may not be properly installed or registered. Error code 0x80040154
