Musescore 3.6.2 will not install on my Windows 10 PC.
When I double-click on the installer file, the only thing that happens is an error message that pops up.
In case this is helpful in diagnosing the problem, the error message says: "This installation package could not be opened. Verify that the package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer package."

In this case it might be useful to download the installer again from this site.

I just tried it. Same message/problem.
And in case of a 32-bit Windows make sure to use the 32-bit MuseScore

Also it was the 64-bit version of Musescore I tried to install.

I can't find the "run as administrator" option anywhere under the right-click panel, but I ran it as administrator through the command prompt. Same message/problem.

If you don't have run as administrator under right click on the exe file, it seems to me that there is a problem with your windows instillation. Default cmd prompt is not administrator. You have to raise it to admin level.

I have the "run as administrator" option on .exe files. But this is a .msi (Windows Installer Package) file.
I ran the command prompt in administrator mode when I tried it earlier.
Here are some pics (attached). Maybe they'll help.

From here:

Try the 'Portable version' - no installation needed.

Where did you save the MuseScore msi installer? Hopefully not in the Windows directory (or the System32 folder).
Other thoughts:
Are you running Windows 10 S -- which requires apps downloaded from Windows Store?
Have you tried installing MuseScore using Windows 'Safe Mode'?

First, to answer your questions, I downloaded the file to my downloads folder.
These are some of my Windows specifications:
Edition Windows 10 Pro
Version 21H2
I have now tried installing Musescore using Windows Safe Mode. (It didn't work, in case you were wondering).
Second, after much research, I have installed Musescore 3 successfully on my PC.
To do so, I had to access my administrator account. (It appears there is a higher ranking Administrator account above the "Administrator" account I use normally). This is how I did it:
1. I opened Cmd prompt in admin. mode and typed in "net user administrator /active:yes". (This allows the Admin. account to become visible in the start menu.)
2. I moved the Musescore.msi file to a nice public location (Local Disk C:).
3. I signed into the Admin. account and installed Musescore with no problem at all, it worked exactly as it was supposed to.
4. I signed out of the Admin. account and signed back into my other account.
5. I entered "net user administrator /active:no" into the Cmd prompt. (This hides the Admin. account again).
6. I navigated to the folder where the musescore application was and created a shortcut to the desktop.
7. I checked to see if it ran as a program on this account. It did.
Thanks for all the helpful comments and suggestions. Much appreciated.

Interesting. Thanks for the update. Glad you got it working.
Run as Admin is normally supposed to invoke the higher admin account.
