If you have any security software running on your computer (Comodo, ESET, Norton etc.), you may get warnings saying that DLL-files Fixer is trying to connect to internet and/or make changes to your computer. This is because the Fixer needs to contact our server to download the correct cygwin1.dll file, install it in the Windows system folder and then make changes to the Windows Registry. You should allow the Fixer to make these changes, otherwise your problem may not be solved.
  5. When the Fixer has installed cygwin1.dll on your computer, hopefully, your errors relating to cygwin1.dll will be gone! You will be given the option to scan your computer for more errros. We encourage you to do so. The trial version of the Fixer will fix up to 15 additional errors it encounters. You can later upgrade to the full version for only $29.95 to get unlimited error fixing and DLL-file downloads.
