This worked for me:

1. Browse the registry to HKLM\Software\Policies\Microsoft\Windows\Installer
   Create: DisableMSI       Type: REG_DWORD  value = 0   (0 should allow you to install it was originally 1)

After this try to install any .exe set up & it should work fine.

Try below if above doesn't work;

 Is the computer on a domain?

·        Is the issue isolated to only this software or you get the same error message with other software’s as well?

Try the steps below and check if it helps.

Step 1:

Run the software setup file as an administrator and check if it helps.

a. Right click on the setup file of the software that you are trying to install.

b. Select “Run as administrator”.

Step 2:

Temporarily disable the antivirus software running on the computer and check if you are able to install the software.

Disable antivirus software

Warning:
Antivirus software can help protect your computer against viruses and other security threats. In most cases, you shouldn't disable your antivirus software. If you have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you're connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.

Step 3:

a. Click Start, type "Local Security Policy" (without quotes) and press enter.

b. Click on Software Restriction Policies.

c. In the right pane, double click on the "enforcement".

d. Select “All users except local administrators”.

e. Click Ok and restart the computer and check if the issue is fixed.
