How to Manually Install a Program on PC or Mac
This wikiHow will show you how to manually install a program. If a program or app fails to install while using an app installer, you can manually download the required components and move them to the program directory.
Part 1Manually Installing a Program
1You need to manually download all of the components and required files in order to manually install. Normally this would be done with an app installer but since this is being done manually, you need to have all of the components ready for install. For open source programs, you can find the necessary files on GitHub. For closed source programs, you can find the necessary files on download.com or MediaFire. You can also find the necessary files on the download page for some programs or on an install CD.
2These need to be copied to the Program Files (Windows) or Applications (Mac) directory. To extract the files, right-click and choose "Extract all…" then choose the location and click Extract on Windows. On Mac, right-click and choose "Open with archive utility".
3On Windows, move the extracted files to C:\Program Files (for 64 bit programs) or C:\Program Files (x86) (for 32 bit programs). On Mac, move the extracted files to /var/Applications. You can do this two ways: open C:\Program Files/C:\Program Files (x86)//var/Applications and drag and drop the folder there or use Command Prompt (robocopy %USERPROFILE%\Downloads\Program %PROGRAMFILES%\Program)/Terminal (sudo cp /Users/(username)/Downloads/Program /var/Applications/Program).
4In order for Windows to recognize the program you installed, you need to make a shortcut in Start. To create a shortcut for all users, go to C:\Users\Default\AppData\Roaming\Microsoft\Windows\Start Menu\Programs, right-click and choose "Create shortcut". To create a shortcut for just yourself, go to %AppData%\Microsoft\Windows\Start Menu\Programs, right-click and choose "Create shortcut". Then choose the program you want to launch with that shortcut.
Part 2Manually Removing a Program
1You can find this in the Programs directory (C:\Program Files or C:\Program Files (x86)) (Windows) or Applications directory (/var/Applications) (Mac).
2If the program is big enough, it will tell you to permanently delete the files. Choose Yes.
3To do so, right-click, choose "Empty", then choose Yes.
4Windows will automatically try to clean up broken shortcuts the next time you try to use them, but to be absolutely sure, go to C:\Users\Default\AppData\Roaming\Microsoft\Windows\Start Menu\Programs and/or %AppData%\Microsoft\Windows\Start Menu\Programs, right-click on the shortcut to delete, then choose "Delete" and confirm.
