I have attempted to download and extract various versions of SQL DEVELOPER many many time over. After days of frustration, I thought I would reach out to see if anyone can help. Oracle online patches and such are not helping. The message I get when I double click on sqldeveloper.exe (all versions) is the same... "The program can't start because MSVCR7.dll is missing from your computer. Try reinstalling the program to fix this problem." Since I don't know when to stop, I followed the reinstall advice many times. Is there a solution out there?
