Affected Operating Systems: Windows Vista, Windows 7, Windows 8
A common issue with modern windows Operating Systems is the restriction on software installation.
Often the message "You must logged in as an administrator when installing this program." will pop-up preventing you from installing the software.
There are several ways you can avoid this problem.
Right click on the installer and select "Run as Administrator"
This should raise your level of permission on the system to administrator and let you install.
1. Right-click the installation file (.exe) file and then click Properties.
2. Click the Security tab.
3. Under Group or user names, click your name to see the permissions you have.
3. Click on the Owner tab.
4. Click on the Edit button.
5. If prompted, click on Continue in the UAC prompt.
6. Under the Change owner to section, click on your user account name and click on OK.
You may disable User Account Control (UAC) settings and try installing the program in administrative mode and check if that fixes the issue.
Refer the following article for more information on UAC settings:
What are User Account Control settings?
Note: Make sure you change back the UAC settings back to default.
You may also temporarily the security software installed and try installing successfully and accomplish the same.
Disable antivirus software
Note: Make sure you turn-on the security software.
If none of the above options worked, and you are in a corporate environment, you may need to contact the system administrators and request installation privileges on your machine.
