Rename a Copy of the Most-Recent Adobe Flash OCX File
1. Start Windows Explorer and look for files named \'Flash*.ocx\' in the folder C:\\Windows\\System32\\Macromed\\Flash\\. (\'Flash*.ocx\' means any file whose name starts with the letters \'Flash\' followed by 1 or more digits and/or letters, such as \'Flash9.ocx\' or \'Flash10b.ocx\'). If there is more than 1 such file, identify the file with the most-recent date.
2. Click once on the file's icon and press \'Ctrl C,\' and then press \'Ctrl V.\' (This creates the file \'Copy of Flash*.ocx;\' its actual name is based on the name of the file you just copied.) Click on the new file's name (shown below its icon) and enter \'Flash\' as the new name.

3. Close all open applications and reboot your computer. Rebooting ensures all running software that's not visible to you and that relies on Adobe Flash software is restarted automatically.
4. After the computer restarts, resume running the software you believe was reporting the \'Flash.ocx\' error. If the software no longer reports that error, you have been successful and can skip the remaining steps listed below.
