Thanks you for your response. The name Package1 is just a test, the real package contains several other components and named appropriately, but it was this one that seemed to cause the problem. I started with a new package, added only the unit IPEdit and built it. The compiler added the RaiseComponentsVcl.dcp and a couple other required files. The build had no errors or warnings. When I tried to “Install” the package is when I received the error dialog. This is a brand new install of 10.4.2 and would hope all of my paths are correct. I will check to see that KSVC Lib\RX10.4\Win32 is in the search path. As a test I changed the “Rz” components to standard vcl components and it built and installed without issues.
Thanks again for your time. I have been a Raize user for a very long time.
