[SOLVED] how to fix epic game installer will not install

[sdled]

.msi errors on install on desktop windows 7
will install on windows 7 laptop
could not find any diff in laptop and desktop as far as permission, registry, or dx, basically the laptop and desktop systems are identical setups.
was able to fix by doing the following on desktop:
create log file:
msiexec /i C:\Users\myusername\Downloads\somepackage.msi /L*v install.txt
install msi file:
msiexec /i C:\EpicGamesLauncherInstaller.msi

here is a video of the fix:

2755, 1307, another that i can't remember, but it to had something to do with the disk
funny thing is epic installer is the only one that gave me problems with install.
anything else installed fine.
even tried moving installer to diff drives and locations
if you do the enable modify registry logging be sure to backup registry first, then delete the new registry entry.
if you do the gpedit enable logging be sure to disable after
both cause exssive log files that will eat up space fast
i found the following to be the most effective in troubleshoot & logging msi errors
i ran this:
msiexec /i C:\Users\myusername\Downloads\somepackage.msi /L*v install.txt
searched for return value 3
scrolled up till i found the start of errors
a quick check from here:
windows-installer-error-messages
https://docs.microsoft.com/en-us/windows/win32/msi/windows-installer-error-messages
allowed me to determine the errors and meaning
i also did the following:
Method 1: Add an Installer folder in the Windows directory
Method 2: Check if the setup file is encrypted
Method 3: Add the SYSTEM user in the installer
Temporarily disable any anti-virus software
check DX registry values
then i ran from cmd promt with admin:
msiexec /i C:\EpicGamesInstaller-10.7.0.msi
and the install worked with no errors
on right click of .msi there was no cmd with admin
had to start cmd with admin privileges from start accessories
navigate to folder of installer
and then copy paste the above run cmd
hopes this help others with problems with game installer or any .msi file
