Windows 10: Can`t install new programs, "Windows Installer" can`t be accessed

Hello there,since a few days I can`t install new programms on my Windows 11 Pro. The installation will startup, but then there will be the error "Windows Installer can`t be accessed"I tried to search online for solutions, but most were for other versions of Windows or didn`t work for me.msiexec.exe is running and set to manual. I tried closing it and also unregistering and re-registering. If anyone knows a solution or what could have started it, please help :Best regards

Clean Install Workaround for Vista

You may remember this news story on techPowerUp! a couple of days ago relating to the lack of clean installs when using the Upgrade Editions of Vista, which required an old OS to be installed. However, Paul Thurrott has managed to find a workaround for this issue, which ironically lets users do a clean install Vista without any previous version of Windows, albeit a little tedious. Here are the steps:

• Boot from the Windows Vista Upgrade DVD as normal
• When prompted for a product code, leave this blank
• Select the version of Vista you have purchased and let Vista install
• When you boot to your desktop for the first time, run the Vista setup from Windows
• This time enter your product key
• When asked whether you want to do an Upgrade of Custom install, select custom and choose a clean install
• Windows will now install for a second time and you should be able to activate it

Remember, these steps are only advised for use in order to achieve a clean install of Vista, it is only legal to use the upgrade editions if you have previously purchased the appropriate version of Windows.

Windows Installer Issues! Can´t Install Programs on Windows 11.

Did you see my warning under the WIndows Club link in my last post to avoid Restoro which is a PUP? If you'd miss that I wonder what else was missed. Absolute thoroughness is required in these issues, skipping nothing and asking back if you need any help to complete a step. We often find out later that the fix was the skipped step, so please do not skip any. If you need help performing any step I will help.

I would uninstall Restoro ASAP and run System File Checker/DISM in WIndows 11:

If that doesn't fix it then you can do a Windows 11 Repair Upgrade which reinstalls Windows while saving your files and apps in place, brings it up to the latest version by the most stable method, takes about an hour and resolves most problems: https://www.elevenforum.com/t/repair-install-wi...
