A few simple troubleshooting steps can be used to fix these two Windows errors, which are similar to most other Windows errors.
Make sure to perform the following pre-run checks before starting Edge Chromium to make sure you don’t run into any minor errors that may be preventing Edge Chromium from installing or updating. You should first run a virus scan, malware scan, third-party software scan, etc. If you have any, run a registry cleaner as well.
You may need to uninstall Edge and then reinstall it in order to resolve error 1603 or 0x00000643. If that doesn’t work, the Microsoft Fix It should resolve this issue.
