We have just uploaded OpenSolver 2.8.2, available on our SourceForge site here.
This is a second attempt to work around the “Automation Error” bug that some users are seeing on some versions of Excel. (This appears to be caused by a VBA bug that is corrupting the cached code. We have now “cleaned” the code)
As always, please send us any feedback and let us know if you have any problems.
Thanks very much!
THANKS, great work!!
