Hello all! Got a problem with SmartSDR CAT and I need some help.

Short version:
Installed Windows 11 on my PC today, installed SmartSDR v3.2.39 and cat.exe won't start.

Longer version with more details:
Like I said, I think I have seen something like this before but I can't recall. Running cat.exe it just fails to open.

The errors I am getting are .Net framework errors. However, I am running .Net Framework v4.8.04161

    LOL, Welp! Nevermind. After a bit more research, it looks like running C:\Program Files\FlexRadio Systems\FlexVSP\FlexVSPInstaller_64.msi did the trick..

    Yea, I figured that even though I figured it out just a scant few minutes later, it would be best to leave it, in case anyone else runs across the issue. But everything is rocking along smooth now on Windows 11..

    I also ran into the old portcls.sys BSOD but, that's a limitation in the Windows Audio subsystem and the number of devices it can have. Fortunately, it figured itself out after a couple of reboots.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
