How to tell if MSVCR80.dll (Microsoft C Runtime Library) was uninstalled cleanly

After uninstalling, restart your computer. Then start Windows Explorer and see if there is still a folder with the name of the software under C:\Program Files. Be sure to check the Registry as well for remnants of Microsoft C Runtime Library. To do this, start "Regedit", then look under "HKEY_LOCAL_MACHINE" > "Software" for Microsoft C Runtime Library or the name of the producer. Always keep in mind that only a computer professional should ever directly delete entries in the Windows Registry.

What to do if a program does not uninstall

The easiest way to remove any kind of software cleanly and accurately is to use an uninstaller tool. Because the uninstaller automatically creates a backup, there is no risk of anything going wrong.

Last but not least

If Windows not working quite right for you, or if startup is taking a long time, or MSVCR80.dll is causing problems for you, a good Windows diagnostic tool may very well help. This is especially effective when it comes to older computers that have accumulated vast quantities of "garbage data" as the result of many software installs and uninstalls.
