All Add-Ins works with Outlook® 2002 / 2003 / 2007 / 2010 (32-bit) and the operating systems Windows® XP/ Windows Vista® and Windows® 7. The operating system may be 32 and/or 64 bit.

May be the Add-Ins (partly) runs also with Windows® 98/NT/2000 and server based operating systems. This will not be tested and therefore the support is restricted.

Note: The operating systems Windows® 98/NT and 2000 are outdated and should not longer used. Same is for Outlook® 2002. Who consider to buy new software it is recommended to buy Office 2010 (32-bit) and Windows® 7 (32- oder 64-bit). This combination works stable and causes less problems. All users of Windows Vista® should switch to Windows® 7. Windows Vista® causes the most problems (even Windows® XP is better than Vista®).
