How to Repair Setup.exe

Troubleshooting Install/Uninstall
1. Terminate the program installation and delete the downloaded program. Download the program again and attempt to reinstall to replace missing files that may have been skipped during a previous installation.
2. Close the web browser to work offline if reinstallation is unsuccessful. Disable any antivirus software and firewall programs that may be halting the installation process, and repeat the installation or use the 'repair' feature if it is available. Enable AV software and firewalls before accessing the Internet.
3. Open the 'Event Viewer' to inspect the Windows log for errors that may have occurred during recent installs or uninstalls, or reports of missing .dll files. For Windows XP, the Event Viewer is available by clicking 'Start' > 'Control Panel' > 'Performance and Maintenance' > 'Administrative Tools' and double-clicking 'Computer Management' > 'Event Viewer.' Other Windows versions use similar pathways.
Finding and Replacing a Missing DLL File
4. Open 'Search' from the Windows 'Start' menu and type in the filename of the missing .dll file. Include hidden and system files in the search to locate the file in another program folder.
5. Repeat the search, if unsuccessful, on another computer using the same operating system or Windows version. A version mismatch of the .dll can corrupt the file on one computer, but an intact version can be retrieved from a computer with the same operating system.
6. Search online .dll databases for an unmodified version of the missing .dll. Download the file that corresponds to the Windows OS of the computer with the missing file.
7. Open the program folder of the program with the missing file, and copy the .dll file to the folder. Alternately, open the 'Windows' folder and insert the .dll file in the 'system32' folder. Reboot the computer.
8. Download and install a Registry Cleaner program if reinstallation or replacement of missing .dll files is unsuccessful. Create a system backup when prompted, and run a full system registry scan following all on-screen prompts.
