HT1923 MS Visual Runtime error R6034

Question

Since i-Tunes tried to download an update, I cannot get the application to run at all, even having removed the entire software library in the sequence suggested here, i.e.
(1) i-Tunes, (2) Apple Software Update (3) Apple Mobile device support, (4) Bonjour, (5) Apple Application Support.
Any ideas or suggestions as to how to get over this mess?

Hi,
A runtime error is a software or hardware problem that prevents a program from working correctly. Runtime errors might cause you to lose information in the file you're working on, cause errors in the file (corrupt the file) so you can't work with it, or
prevent you from using a feature. Unlike stop errors, runtime errors don't typically cause Windows or a program to stop working.
1. I would suggest you to try the steps from the following link:

2. I would suggest you to run SFC scan.  SFC scan will scans all protected system files and replaces incorrect versions with correct Microsoft versions.

3.  I would like to suggest you boot in Clean Boot Mode to check the issue.

If the issue disappears in the Clean Boot environment, we can use a 50/50 approach to quickly narrow down which entry is causing the issue.
Meanwhile, you may refer to the links below to check the issue:
