2] Change Registry setting

Hit the WINKEY+R button combination to launch the Run utility, type in regedit and hit Enter. Once Registry Editor opens, navigate to the following key-

Computer \ HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ SideBySide \ Winners \ x86_policy.9.0.microsoft.vc90.crt_1fc8b3b9a1e18e3b_none_02d0010672fd8219 \ 9.0

Now, check if you find a String value named as default

Double-click on it and change its Value data to match the one as the third value in BINARY as shown in the screen snippet above.

Reboot your computer for the changes to take effect.

3] Reinstall the appropriate Visual C++ Runtime

Start by opening the Event Viewer by searching for it in the Windows 10 Search Box.

Look up for the error events which are sourced by SideBySide.

Find the actual Visual C++ Runtime module causing this error.

Then download that particular module from official Microsoft Support here.

4] Re-enable Microsoft .NET Framework

You have to disable and reenable the latest version of .NET Framework on your computer and check if that fixes your issues.

Hope something helps!
