Error: Can't set the installed property of the add-in.

Updated: March 16, 2009

Issue: I've seen the case where a user tries to open an Excel document from within a binder and receives a message similar to this one.

"Can't set the installed property of the add-in."

Cause: This is caused when Engagement's add-in becomes disabled for one reason or another.

Resolution: This is an Excel error and can be resolved by:

1. 1. Close all instances of Excel (This especially applies to all users with "Launch separate instances of Excel (Dual Monitors)" checked under Tools Options General)
   
2. 2. Open Excel from outside Engagement
   
3. 3. Go to Tools Add-Ins
   
4. 4. Make sure "Epace" is checked
   
5. 5. Click OK
   
6. 6. Close Excel

Additionally, go to Help About Microsoft Excel Disabled Items. Make sure Epace.xla is not listed as disabled. If it is, select it and press Enable.

This should solve the problem.
