Where to start? - I had been trying to breathe new life into my venerable laptop (running XP SP3) by installing Softphone software so I can (Video)chat with friends. Ran into trouble, tried to fix it myself, Google just made matters worse.
I can tell you this much;
- Start/Run/msconfig gives error message "...Not Found..."
- Registry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows\CurrentVersion\App Paths\MSCONFIG.EXE ; in my App Path, MSCONFIG.EXE does not exist
- My Computer/Properties/Advanced/Environmental Variables/Path/Edit ends in "Program Files\Quicktime\QTSystem\" rather than just "Program Files\"
- Start/Run/sfc/scannow hangs up several times with message "Files that are required for Windows to run properly must be copied to the DLL cache - Insert CD now (I don't have the install disk)
- Malware removal tools fail to install with error message as follows: CoCreateInstance failed, Code 0x80040154 Class Not Registered; further fails with message "Run-Time error '372' Failed to load control 'WebBrowser' from ieframe.dll. Your version of ieframe.dll may be outdated. Make sure you are using the version of the control that was provided with your application.
- Could not fully Uninstall certain applications. Resorted to DOS ATTRIB CMD to manually delete.
Have run or attempted to run several different free on-line products such as Windows Defender, IoBit ASC, AVG, MalwareBytes, McAfee Stinger, etc in no particular order. Sometimes they will install and other times they won't. Sometimes they show a virus being removed, usually they do not. I generally uninstall them after use so as to not conflict with other products. Additional anecdotes available upon request. My bad for not keeping a log of error messages, failures, etc, but what was done (or not done) is done.
My apologies for not adhering to the "One Post, One Problem" rule, but I figure that the more concurrent symptoms you are aware of, the more likely it is that you will recognize the scenario and know where to start.
If you have the fortitude to see this through to the end, your assistance would be greatly appreciated.
A little knowledge is a dangerous thing...
