I had to format my hard drive, and I want to re install TDS3 ( also Port Explorer) when I try to instal TDS I get this message. C\Windows\system\msvbvm60.dll An error occured while trying to replace existing file. Delete File failed:Code 5 Access denied. Then a message about click Retry. Abort Ignore. I have tried moving/ renaming/ deleting this file but keep getting the message "this file is being used by windows" Any ideas?
