Hey everyone,

The above all was good. One extra step was required after issuing the commands thomas suggested. Go to C: -> WINDOWS -> system3 and you can now see the cyg files. Right click -> Properties -> uncheck read-only. Now re-issue the commands given by thomas:
”
- Start > Run… > cmd (hit enter). Then in the command line, type:
- cd c:\windows\system32
- attrib cyg*.dll -s -h
- del cyg*.dll
“

Like everyone else has said: Thank you! I just came across this problem myself, and even after deleting a bunch of erroneous cygwin1.dll files (lots of random programs seem to have their own version), I was still hitting this error. I found the cygwin1.dll file in system32, but even after making sure that I hadn’t accidently switched to Idiot Mode, the file was still hidden – good call, Microsoft, users really don’t need to see their files! Maybe Vista can come with an automatic rootkit and save all the hacker/crackers the trouble?

Anyway, thanks Melissa A, your message solved my problem.

WinXP – Can’t delete it? Here’s how.

- Reboot in Safe Mode
- Start > Run… > cmd (hit enter). Then in the command line, type:
- cd c:\windows\system32
- attrib cyg*.dll -s -h
- del cyg*.dll

That worked for me at least
