windows installer could not be accessed windows 10

I wish that Microsoft just had a package to reinstall msiexec, but it seems as though they haven't done that since Win7. Microsoft also unveiled the concept of a universal Windows app. I'm guessing that those utilize an MSI in some way? Myerson said that these changes would occur in a future update, but did not elaborate. Stop and start msiexec service unregister and re-register msiexec (both x86 and 圆4 copies) Import registry settings from a known-working computer (specifically the key msiserver)Īs a side effect, it seems as though some control panel items no longer work, and internet explorer doesn't work properly either. Click on Services and scroll to Windows Installer.

Step 1: Try to ensure that Windows Installer service is running. I have followed all of the steps outlined by Prajwal here: If the above does not work then follow these steps and try to install after each step. This was originally discovered after upgrading a computer from Windows 7 to Windows 10, though it has since occurred on a computer that was always on Windows 10.

I have had several computers stop being able to install or uninstall anything that utilizes an MSI file. I am writing this post as I have now run into this issue several times with no solution in sight.
