How to uninstall/reinstall C++ modules

1. Open Control Panel and click on Programs and Features

or

2. In the Upper right corner of the window look for this:

3. Click in the box and put in C++ then click the arrow or hit the Enter key to filter your results to only the C++ modules

4. Now Uninstall all existing C++ from Control panel, starting with the newest (2017) and work your way through the list

I generally see mismatches or items without file sizes when I know there are issues. Right mouse click and follow the prompts to Uninstall (not repair) the installed C++ Module(s).

5. Then Go here:

and click on this link:

6. Download the Visual C++ v56.exe in the screen that comes up (be patient, the download will start. Once downloaded, then we need to get the additional runtimes that have been released)

7. https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads
Go to this section "Visual Studio 2015, 2017 and 2019" and download these updates:
x64: vc_redist.x64.exe
and
x86: vc_redist.x86.exe

8. Navigate to the Downloads folder, right mouse click on the Visual C++ v56.exe and select properties and in the box that pops up, you must unblock the file:

9. Repeat this process for the other two downloads from step 7 as well.

10. Once unblocked, right mouse click and Run As Administrator (do not forget this step) on the Visual C++ v56.exe

11. It will unpack the files and open a CMD window:

12. If you have just uninstalled the C++, you will have the option to Ignore (I), select that or Y for yes

13. Then in the next screen type Y again to proceed and let it run through the installer then click any key when prompted to close the installer

14. Go back to Control panel => Programs and Features and filter for only C++ and ensure there are 18 components now there.  If there is not, then there is an issue on that system and may need to manually install any components (x86 and x64) that do not have a match from here: https://knowledge.autodesk.com/search-result/caas/sfdcarticles/sfdcarticles/How-to-remove-and-reinstall-Microsoft-Visual-C-Runtime-Libraries.html

15. Now repeat the process for the vc_redist.x86.exe & vc_redist.x64.exe, and simply follow the installer instructions

16. Reboot the machine (to ensure the changes are fully implemented)

17. Retest and see if that resolves the issues you were experiencing.
