June 28, 2013: NPGS Update v9.1

The latest free update of NPGS v9 is available that adds enhancements including additions to the NPGS Manual. A complete improvement history is available on the update web page.

September 21, 2011: 64 bit Windows 7 Home Premium

Previously, 64 bit Windows 7 Home Premium did not allow an 'office' installation of NPGS to work properly. It has now been confirmed that 64 bit Windows 7 Home Premium (Service Pack 1) allows an 'office' installation of NPGS v9 to work without any special configuraiton changes.

October 1, 2008: Keithley 6485 Picoammeter

Software to communicate with a Keithley 6485 Picoammeter through a serial port is available with NPGS at no charge. Current users can send e-mail to get a copy of the new software at no charge. The current release of NPGS also includes a feature to allow the user to call the new software so that multiple readings from the picoammeter can be averaged and automatically entered into the NPGS software before a pattern is written.

October 29, 2004: False Virus Notification about "encrypt.exe" in DesignCAD LT 2000

{Update: This issue does not affect the newer DesignCAD Express v16.2 which can also be used with the latest release of NPGS.}

Recently, virus scanning programs have been flagging the "encrypt.exe" program within DesignCAD  LT 2000 as having the "W95.CIH.remnants" virus. In some cases, the scanning software prevents DesignCAD LT 2000 from installing properly.

In all cases, the "W95.CIH.remnants" notification means that the affected file at one time had the "W95.CHI" virus, however, the virus was removed (in this case, many years ago) and is no longer active. However, the virus scanning software is now treating the file as though it still has an active virus, which is inappropriate. The bottom line is that when the original virus was removed, some inactive bits of the virus were left in the file, which is what is now being treated as an active virus.

If DesignCAD LT 2000 is already installed, you can simply have the virus scanning software delete the "encrypt.exe" file, since it is not used by NPGS anyway.

If you are trying to install DesignCAD LT 2000, do the following: 1) Disable the active virus scanning; 2) Install DesignCAD LT 2000; and 3) Re-enable the virus software. Subsequently, you can delete the "encrypt.exe" file.
