- The following message appears when opening an Excel section:
- "Smart Builder cannot connect. Please close all Excel instances before opening an LMS Section!"
- The Excel section opens but Smart Builder does not function
- Once the error occurs, it persists until the user completely exits (not just logs off) and reloads the NuGenesis LMS client
- NuGenesis 8 LMS SR2
In NuGenesis 8 LMS SR2, a change was made to the client so that, by default, it starts an Excel automation process when the LMS client starts, and the Excel process keeps running until the LMS client shuts down. Previously, an Excel process started on-demand each time a user opened an Excel section in NuGenesis, and the process was closed when the section was closed. The LMS client and Smart Builder communicate by sending messages to local host and a dynamic port number. Because SmartBuilder is keeps running, its port number for internal SDK communications can become out of sync with the LMS client, leading to these symptoms.
FIX or WORKAROUND
- Defect report CRI-25 was filed for this issue.
- Revert to pre-SR2 behavior by setting the "PrestartExcelAndKeepAliveForEdit" registry key to FALSE
This registry key has no effect on NuGenesis 8 ELN SR1. The behavior described in this article was implemented in NuGenesis 8 LMS FR1. The key reverts the behavior of LMS to that of ELN 8 SR1; therefore, these keys have no effect on SR1.
