When SolveXL Add-in does not appear in Microsoft Excel after a successful installation then very likely a 32-bit version of Microsoft Excel was not installed on the system. SolveXL does NOT support 64-bit versions of Microsoft Excel.

Users experiencing problems with SolveXL Add-in (e.g., toolbar buttons not responding) are recommended to disable other COM Add-ins that might be affecting SolveXL. More specifically, occassionally conflicts with Microsoft Solver Add-in were reported by some users and disabling the Add-in has solved the problem.
