3. Open an administrative command prompt (open Command Prompt using right-click, “Run as administrator”)

4. Within the administrative command prompt, navigate to the installed SAP2000 64bit directory. This will probably be similar to “C:\Program Files\Computers and Structures\SAP2000 18”

5. Within the administrative command prompt, run “UnregisterSAP2000.exe”

6. Copy the new registration files into SAP2000 18 64bit directory, overwriting the existing files. You may need administrative rights to do this.

7. Within the administrative command prompt, run “UnregisterSAP2000.exe”, again. This is one of the new EXEs.

8. Within the administrative command prompt, run “RegisterSAP2000.exe”. This is the other new EXE.

9. Add a reference to the newly created SAP2000v18.TLB to your Excel project.

10. You should now be able to launch or attach to SAP2000 18 64bit from Excel 32bit, using the Helper as documented in the “CSI_OAPI_Documentation.chm” file.
