My girlfriends computer, upon startup, would always give me a Msvcr71.dll error. In my case it was related to the free Avast Antivirus that was on my startup list. I know it was related to the Avast because it was the only thing checked on my startup list in msconfig. Well, along with normal things that needed to be there. Side note, I would also get the same error when I tried to start her AIM Messenger (Msvcr71.dll missing).
After having the problem for a couple weeks and trying to do some research and troubleshooting BEFORE I posted my problem on BC I finally fixed the problem this morning. I went through some of the forums on BC and some other sites and tried all the recommendations to no avail. Downloading a new dll from www.dlldump.com. Renaming my old Msvcr71.dll. Unregistering it. Registering it (to which I would receive the LoadLibrary error noted in the Topic Description line). Searching to to see where it was located using Windows Explorer. On and on and on, over and over again. All these avenues left me high and dry and STILL with the same error.
So, what cured the problem was this. I read a forum about having AVG Antivirus installed and the trouble some people had with trying to remove it in normal startup and how it failed. The same thing happened to me when I tried to remove it. They recommended starting in safe mode and removing it that way. Before I shut down I removed Avast Antivirus and tried again to remove AVG Antivirus, but it would not let me remove it. Off to safe mode we go. In safe mode I removed AVG Antivirus. Success! No failure errors. Back to regular startup (Is there a tech term for "normal startup" that someone reading this can inform me of? Thanks.) Upon regular startup, again, success! No failure errors. I downloaded Avast Antivirus and I was good to go. No more Msvcr71.dll errors.
FYI for anyone with a similar problem.
