How to Remove Nvcpl.dll

1. Right-click on the 'Start' button in Windows, and select 'Explore' from the pop-up options. In the Windows Explorer window, navigate through the folders in the left panel to find the system folder for your version of Windows. Its location varies by system version; in 32-bit XP and Vista, it's 'C:\Windows\System32.' In 64-bit XP and Vista, it's 'C:\Windows\SysWOW64.' In 2000 and NT, it's 'C:\WINNT\System32.' In 95, 98 and ME, it's 'C:\Windows\System.'
2. Left-click on the system folder in the left panel to highlight it, then start browsing through the files listed in the right panel until you find nvcpl.dll. Right-click this file and select 'Delete' from among the options that pop up.
3. Left-click the 'Start' button in Windows and select 'Run' from the Start Menu. Type 'cmd' in the Run window and click the 'Run' button. This will launch the command prompt.
4. Type 'regsvr32 /u C:\Windows\System32\nvcpl.dll' into the command prompt if you are using a 32-bit version of XP or Vista. If you're using another version of Windows, simply edit the file path part of this command line to reflect the file path associated with your version of Windows in Step 1. For example, 64-bit XP users would type 'regsvr32 /u C:\Windows\SysWOW64\shell32.dll' instead. After you enter this line, press 'Enter' to un-register the .dll and complete the removal process.
