The memory error is not a result of the amount of RAM on your system, but a 32bit application OS limit. A 32 bit application can only access 3 GB of RAM and it sounds like you are hitting that limit. Please download the SPB 17.2 version of PSpice which is a 64 bit application and will utilize all available RAM. You can download a copy from
Micro-Cap 10, 11, and 12 are now free and require no key. You can download the full CD or the executable only. Full CD: Use this option if you are new to Micro-Cap or want a fresh install. Download the CD and unzip it into a separate folder. Execute the setup.exe program to install the entire program including libraries, sample circuits, and manuals. Make sure you install to a non-write-protected folder. Note that Windows Program Files is a write-protected folder, so install somewhere else. Executable only: Use this option if you want to retain your old library edits. Download the ZIP file and copy all its files into your current Micro-Cap folder, replacing the old .EXE and .DLL files. This option is also available from within Micro-Cap at Help menu / Check for Updates. Older versions of Micro-Cap (MC5 through MC9) downloads are available but still require a key.
The Haspdinst.exe file present in the ZIP file needs to be run with the command switch '-i'. Click on the Start menu in Windows and select the Run option in the menu. In the Run dialog box, enter the full path (either manually or through the Browse option) for the Haspdinst.exe file. At the end of the string, hit the spacebar, and then type in -i. For example, if the files in the ZIP file were extracted to the path C:\HASP, the Run dialog box should contain a string such as: C:\HASP\Haspdinst.exe -i If Windows has placed double quotes around the path and file name, the -i must be placed outside of the quotes. This installs the latest security key driver which must be present to run the update. If this does not work, remove the old driver and then reinstall the new one as follows: %path%\Haspdinst.exe -r This removes the old driver. Then to install the new driver, type: %path%\Haspdinst.exe -i where %path% is the location that the files were extracted to. A message should appear that states the driver has been successfully installed.
In 1999, LTspice III was released, the first public release.[1] It is designed to run on Windows 95, 98, 98SE, ME, NT4.0, 2K, XP. This version is no longer available for download from Analog Devices. Initially, LTspice III was internally released to Linear Technology's Field Application Engineers (FAE) in October 1999, who then gave it away during customer visits via CDROM media.[1] In June 2001, it was released for public downloading from the Linear Technology website.[1][9] Originally, LTspice/SwitcherCAD ran only on Microsoft Windows platforms, but since 2003 it is able to run under the Wine Windows compatibility layer on Linux.[11]
In 2008, LTspice IV was released.[1][7][12] It is designed to run on Windows 2K, XP, Vista, 7 with a processor that contains a minimum instruction set similar to a Pentium 4 processor.[13] Though IV is still available for download, it is no longer maintained. LTspice was originally called SwitcherCAD, but that name was removed when IV was released.[1] A native Apple macOS 10.7+ application was introduced in 2013.[14] 2ff7e9595c
