When I run the function vision.PointTracker, I get the error message: Can't reload 'C:\Program Files\MATLAB\R2018b\bin\win64\ocv.dll'. I already reinstalled matlab, but that did not solve my problem. I use Matlab R2018b. On my other laptop with R2018a, I do not get the error message. What can I do to solve the error?

Thanks for your note, Walter! I have not been able to reproduce this on a Windows 7 SP1 machine (which I know is not a Dell laptop). As far as I can tell, this is independent of Simulink, but I agree that there could likely be other root causes of this problem that I'm not aware of, yet.

This happens due to the unavailability of the Visual C redistributable DLLs, which can be downloaded from here:
For more details about what changed, see the following:
Upon the installation, restarting MATLAB should resolve this problem. Please report back here if the problem persists in spite of installing this. Thanks!

Dear Unner Sajid,
I am facing issues installing C redistruable DLLs.
Can you extend your support to me.
Your efforts will be highly appreciated.
Thanks & regards,

In https://www.mathworks.com/matlabcentral/answers/127222-cannot-launch-simulink-after-upgrade-to-r2013a#comment_782941 I linked to the current Microsoft document on where to download the redistributable appropriate for your operating system and the Visual Studios version in use. What difficulty did you encounter when you installed? Which operating system are you using, and which MATLAB release are you using?
