I've received a few questions about PyXLL's support for Excel 2010.
PyXLL does work with Excel 2010 Professional 32-bit Edition. It has been tested with several of the beta versions, and with the final release 14.0.4760.1000 32-bit and there are no known problems.
64-bit builds are not currently supported however. If you have the 64-bit version of Excel 2010 installed PyXLL not currently work with it.
Home and Student and Home and Business Editions use the Microsoft Click-To-Run technology, and these versions have known problems XLL add-ins, including PyXLL.
If you are using either of the Home and Student or Home and Business Click-To-Run editions you need to uninstall Office 2010 and reinstall the MSI-based version as described here:http://office.microsoft.com/en-us/excel-help/click-to-run-switch-to-using-an-msi-based-office-edition-HA101850538.aspx
To check what version of Excel 2010 you have installed, go to the Help menu under the File menu in Excel.
Of course if you do experience any problems at all, please let me know.
** please check you are using version 1.1.1 of PyXLL for use with Excel 2010 **
