I tried to install the Samsung Kies software on my Windows 7 computer and found that it stuck at part of the installation that said “Installing Hotfix…”. It endlessly stayed at this screen and clicking Cancel did nothing. Here’s what I did to fix the issue.
1. Right-click the time in the lower right corner of the screen or press CTRL + ALT + Delete.
2. The Windows Task Manager will appear. Select the Processes tab, then select the Kies process.
3. Select End Process and the endless install should close.
5. Attempt to install the Samsung Kies software again. The installation should successfully complete this time.
