R help - Jun 2009 - biOps load failed after being used for one week

Hi,

I installed biOps on my XP, and installed the required dll packages,
jpeg62.dll, libfftw3-3.dll, and libtiff3.dll, as suggested by this forum.
Then it worked perfectly for about one week till this afternoon. When I
tried to load biOps again, I got the following error message again

Error in inDL(x, as.logical(local), as.logical(now), ...) : 
  unable to load shared library
'C:/PROGRA~1/R/R-29~1.0/library/biOps/libs/biOps.dll':
  LoadLibrary failure:  The specified module could not be found.


Error: package/namespace load failed for 'biOps'

I saw the same error message before I installded the above three dll files.
Then I checked the dll files, they are still there. I checked the PATH, and
the PATH includes the path to the folder where I put the dll files. 

It's very amazing to me, since biOps worked on the same computer for about
one week till this afternoon. Then I tried to install biOps on my another
laptop with the three dll files installed, and biOpst does not work on my
laptop this time.

Does any of you have any idea or suggestions? I even re-downloaded the three
dll files from the websites in case the three I have were contaminated
somehow.

Any help if greatly appreciated!

Michelle

With help from my colleague, I found the problem. After I put another library
dll, zlib1.dll, at the folder, biOps is working again now. Though it's still
amazing to me why biOps worked for about one week before I had zlib1.dll.

I hope message could also help people who have the same problem.

Thanks,

Michelle
