Hmm… I would try to search the for the .dll on the PC. If you find it, I would try to reinstall VS 2005. The problem doesn’t sound like it’s from Blender. BTW, I wouldn’t download version 2.45RC yet, stick with 2.44 for now.
do a search on google for dll downloads
download the .dll file that is missing
put it in your windows/system32 folder then try it
if that doesnt work put it in your blender dir
