Installer service could not be accessed



Windows Error 1621 happens due to the Windows Installer service fails to access the files which are required while install software into the PC. Windows Installer service is an automatic service by default which starts when Windows starts, but sometimes if Windows system files got misconfigured or infected by virus or spyware then the Windows installer service crashes and it stops working.

To solve this issue follow the below steps:

1. Right click on My Computer and click on Manage

2. Click on Services and Applications and Double click on Services from the right pane to open Service console

3. Scroll down to find Windows Installer, select it and right click on it and click on Start (if it’s not started) or Restart to refresh the service.

This can solve the problem and now try to install any software.

If not solved the issue yet then you need to fix the Windows registry which can be done with various software. You can find and download one of those from the internet and fix your Windows registry and then you will be able to install softwares without facing any error.
