RFsim99 download URL

[cdev]

This seems like a good site to download what is essentially abandonware. But RFSim99 is an extremely useful program..
"RFSim99 is a  free linear S-parameter based circuit simulator offering schematic capture, simulation, 1 port and 2 port S-parameter display and file support, tolerance analysis, stability circles, and much more.
 ]Very easy to use and convenient.
 
Calculate air inductance, PCB square inductance an capacitance, filters, couplers, attenuators, splitters, transmission line, match, etc. Calculator embedded."


I am pretty sure that this site is where I downloaded it first several years ago.

It seems to be mentioned on other sites as the best place to get it.. example

It might be worth comparing MD5 checksums against the installer version.

eg I have V1.05 here and I think I have had this for many years.

The MD5 for my installer file is
EE112A4756D097C6958A7971647884CC

This was taken from an old backup CDROM I burned back in 2001.

It looks like the setup program for RFsim99 won't work any more on 64-bit Windows (it didn't on my Win7 Pro laptop). Some searching led me to this:

It seems like it's only the installer's 'setup.exe' that won't work, the actual installation will proceed just fine once a 32-bit installer is provided. The link above gives some notes on how to do this (I followed the 'InstallShield 3 shortcut' method).

Hmm, I was not able to get the 'InstallShield 3 shortcut' method to work. Anyone else have an luck installing RFSIM99 on Windows10?

RFSim99 has been my go-to for quite some years, but occasionally I stumbled upon weird compatibility issues with Win10, bugs and issues that unfortunately will never be fixed.

As replacement tools, I can strongly recommend SimSmith and QUCS, as they are active and are packed with features!

Furthermore, the authors and contributors to SimSmith have published a lot of tutorials, examples and use-cases.
