Camtasia stops working windows 7 + .Net 4.7, and how to solve the problem

Abstract

Camtasia (TechSmith) 8.6 stop working on my Windows 7 and can not edit mp3 file on Windows 10. The problem on Windows 7 was caused by .Net 4.7 update. I have my solution for Windows 7 + Camtasia 8.6.

Problem details

I realized that Camtasia 8.6.0 stops working at 2017-6-14, after a Windows update on my Windows 7 machine. I see the following window when I started Camtasia.

I have a problem with Camtasia 8.6.0 on Windows 10, that mp3 file are frequently truncated. I like the software, especially I like the caption editing capability and figure overlay for educational video editing. I usually try to use some free software, but this one is exceptionally good, so I bought the software a a few years ago. But I don't need the animation and transitions. So I didn't update the software to 9.x.

But this time, I cannot start Camtasia on Windows 7. I have a mp3 editing problem on Windows 10. So, I just tried the free trial version. However, on Windows 7, the installer even doesn't start.

Camtasia 8.6.0 crashes when start up 

On Windows 10, the mp3 truncated problem seems solved. But if it doesn't work on Windows 7, I have no motivation to upgrade it.

I checked Windows event log, then, I found the following error.

From this, I suspect .Net problem, I checked recent my software and windows update, and found I have .Net update.

Solution

I remove the .Net 4.7 from the Uninstall Program. Then I install the Camtasia 9 free trial version. But I think re-install 8.6 might work, too. Camtasia 9 free trial version first installs the .Net 4.6, which works fine. When the Windows update asked to update .Net, do not update 4.7, but you can get security update for .Net 4.6.

PS

After all this problem, I decided to update my Camtasia to version 9. Let's see I like the 9.x or not...

Why A^{T}A is invertible? (2) Linear Algebra

Why A^{T}A has the inverse Let me explain why A^{T}A has the inverse, if the columns of A are independent. First, if a matrix is n by n, and all the columns are independent, then this is a square full rank matrix. Therefore, there is the inverse. So, the problem is when A is a m by n, rectangle matrix.  Strang's explanation is based on null space. Null space and column space are the fundamental of the linear algebra. This explanation is simple and clear. However, when I was a University student, I did not recall the explanation of the null space in my linear algebra class. Maybe I was careless. I regret that... Explanation based on null space This explanation is based on Strang's book. Column space and null space are the main characters. Let's start with this explanation. Assume  x  where x is in the null space of A .  The matrices ( A^{T} A ) and A share the null space as the following: This means, if x is in the null space of A , x is also in the null spa

Gauss's quote for positive, negative, and imaginary number

Recently I watched the following great videos about imaginary numbers by Welch Labs. https://youtu.be/T647CGsuOVU?list=PLiaHhY2iBX9g6KIvZ_703G3KJXapKkNaF I like this article about naming of math by Kalid Azad. https://betterexplained.com/articles/learning-tip-idea-name/ Both articles mentioned about Gauss, who suggested to use other names of positive, negative, and imaginary numbers. Gauss wrote these names are wrong and that is one of the reason people didn't get why negative times negative is positive, or, pure positive imaginary times pure positive imaginary is negative real number. I made a few videos about explaining why -1 * -1 = +1, too. Explanation: why -1 * -1 = +1 by pattern https://youtu.be/uD7JRdAzKP8 Explanation: why -1 * -1 = +1 by climbing a mountain https://youtu.be/uD7JRdAzKP8 But actually Gauss's insight is much powerful. The original is in the Gauß, Werke, Bd. 2, S. 178 . Hätte man +1, -1, √-1) nicht positiv, negative, imaginäre (oder gar um

Why parallelogram area is |ad-bc|?

Here is my question. The area of parallelogram is the difference of these two rectangles (red rectangle - blue rectangle). This is not intuitive for me. If you also think it is not so intuitive, you might interested in my slides. I try to explain this for hight school students. Slides:  A bit intuitive (for me) explanation of area of parallelogram  (to my site, external link) .
