Mainpine IQ Express (Rev3) Driver for Windows 8 / Server 2012

16 May 2013

Valued Customer,

Mainpine is pleased to announce the release of our newest Windows driver for our IQ Express (Rev3) fax boards.  This driver release includes support for Windows 8 and Windows Server 2012 (as well as all Windows versions from XP through Server 2008 R2 - both 64-bit and 32-bit).  This driver version fixes minor "blue-screen on shutdown/restart" bugs that were present in the MPCD20MAR09/ driver (which was previously the latest driver which worked on Windows 8 and Server 2012).  It also adds a new feature which is capable of electronically identifying the serial number of most IQ Express (Rev3) fax boards.

This driver is technically still in "beta" phase as it is not yet made it to our production operations (when it will be included on the CDs shipped with new product); however, all Windows 8 and Windows Server 2012 users are encouraged to update to this at their convenience by following the driver update instructions below.  Once Mainpine pushes this driver into our production operations the older drivers will be moved out of the mainstream downloads page, and this driver's "beta" tag will be dropped.

As the IQ Express driver has very little to do with operational reliability within the fax application, users are strongly cautioned against perceiving this new driver as a solution for any unreliable fax application operation.  Users who are experiencing unreliable fax application operations (trouble sending or receiving faxes within the fax application) are advised to utilize the Mainpine Production Testsuite CD (also available on the downloads page) in order to test the hardware and fax lines.  Such users who are running Windows Fax Service should also ensure that they are using Mainpine's IQFSP software (also available on the downloads page).

All software and driver downloads are available at: Username: "customer", Password: "iqexpress".

Please see below for the driver update instructions.
