Introduction to "Valvalyzer" a Windows workstation vacuum tube and stage simulation software package written by Jim Reese from AmpCad.com

It takes about 50 seconds to transfer the files, then the updater will launch the application, but there is a significant pause there where you might think it crashed. Look in C:\Valvalyzer\Distribution and see if the files are there. If so, you can double-click on Valvalyzer3rdEdition.exe.
if you didn't have net 4.8.1 installed, the updated wouldn't even try to run.

There are the files but nothing with double click on Valvalyzer3rdEdition.exe. I confirm 4.8.1 installed
Maybe antivirus problems? ( Avast )
No Valvalyzer icon, only V updater
 
This is really curious. The same files load and launch fine on my Windows 10 computer. Do you have a Windows 10 computer that you can try installing on? Also, there is no Valvalyzer icon, only the Updater icon which ensures updates are distributed as necessary. You can aways run Windows Defender on any file if you fear a virus. I have a feeling your Windows 11 is prohibiting execution in C:\Valvalyzer\Distribution because of folder access restrictions. You can manage these restrictions yourself in the control panel. I get this all the time. You can move or copy the Distribution files anywhere on your C: drive and try running them in the same manner, just a different location. Sorry for all this difficulty.
 
I uninstalled Avast but the problem remains the same, when I launch V updater the application works for about 50 seconds, then the message " Starting Valvalyzer, please wait " appears and after a few seconds crashes. No Valvalyzer icon, only V updater. I changed the location of the Valvalyzer folder, the song remains the same...
 
Sorry for all this difficulty.
Don't worry, this is what a team of testers is for and debugging takes time. Some of the members here will relate.

So please forgive my insensitivity if I advise you I'm having a minor issue with your website. The elements appear to not be resilient to custom font settings.

I have a modern i7 processor laptop with 16GB memory on Win11. My monitor has 3840x1200 pixels resolution connected via USB-C. I downloaded Valvalizer through the above buttons (Download Valvalizer) and I got the Valvalizer Updater, that starts to update. It took a while, then I got a message that Valvalizer was starting but after a while nothing happens or comes up. In the Task Manager no sign of application activity and no C:/Valvalizer/Distribution folder either.
 
I've never seen that before. What do you mean by custom font settings?

I don't think you're insensitive, in fact you've been really tolerant of my sloppy deployment. The website also has a nasty page-time-out problem that Copilot has supplied several exotic suggestions, but the main remedy seems to be to just refresh the home page manually.

If you'll hang in there with me, I might have some good news. And this is good for Horneydude too. I consulted with Copilot this morning about the Windows 11 issues, and it seemed to be fully aware of the problems and even provided several code fixes to prevent Windows 11 from tagging EXEs with a Zone.Identifier alternate-data stream. (Isn't it always something?) The missing C:/Valvalizer/Distribution folder could be that I need to ask for "elevation". Jeez.

I will crank in these changes to the updater today, then ask for your indulgence to test it out.
I am at your mercy, and I am really grateful for your help. I should have a Windows 11 computer, but I've been busy, and I am a terrible procrastinator. After years of development, I am just itching to get this app out into the world. Never mind I'm tripping on my shoelaces.

Meanwhile, Windows 11 owners should wait until these issues are resolved. The car is in the garage.
 
analog_sa, I've been anticipating this question forever, and I can give a few reasons. I understand that post#1 is full of blustery marketing language and no substance. I'll fix that.

Being a programmer and a hardware designer, I have been aware of spice, but not a devotee. I tend to avoid awful programming languages, and spice looks like a compete cryptic mess. In fact it's so awful and tedious, it was a key inspiration for me to develop Valvalyzer, which is a real-time, graphical interactive platform for simulating devices and stages with no need to write any code or import any libraries. In fact, its parametric design methodology, which consists of simple data entry, is instructive and educational in itself. All the work you would do coding spice is done for you under the hood.

Plus, Valvalyzer has the ability to design transformers and provide fabrication reports.

I encourage you to download the User Guide, and you will see what is extremely hard to put into a few words. And thanks for the question! Jim Reese (ampcad.com)
