Thank you Craig. Copying them into the application folder solved the problem. -Joel

>>I've been using vfpencryption71.fll for a few months and am now encountering the error "FLL is invalid." It seems that what is causing this error is a missing file, msvcr71.dll, the Visual C++ runtime required for this FLL.

>>So my question is, how do I install msvcr71.dll on a newly configured computer? I've searched the web for a distribution file that will install msvcr71.dll to no avail.

>As Sergey has already said you need msvcr71.dll and msvcp71.dll. I usually put them into the user's system32 folder if they don't exist, but if I run into some DLL hell, I will toss them into the application folder as Sergey suggested. There never was a Redistributable package I don't think (saw a hotfix for SP1 once, closest I ever saw to anything that could be distributed to end-users), so I think the idea is to just grab them from your dev machine and pass them across to the users (assuming of course that you can't just use a merge file in your applications Install in order to more properly distribute the C/C++ runtimes).
