Windows 2008 R2 server
Can not apply formatting in active forms for TM1.
Before installation of TM1, you need to install Microsoft Excel on the TM1 server to make Tm1web work.
Active Forms formatting does not work if you have a language specific Excel version, you must install a Microsoft Excel Multilanguage version.
Recommend that to any Tm1 installation, always install the Microsoft Office multi language versions of Excel 2010.
