Hi All

We have an app in VFP versions 8 and 9. A few users who install MS Office 2007 are getting a strange error when running our app when our app tries either to run the Dynazip unzip/zip ocx or when it tries to access certain WinAPI functions like ShellExecute(). There are two errors:

1) "Couldn't find library MSVCR80.DLL (required by ...\Office12\GrooveUtil.dll)"

2) "Couldn't find library MSVCR80.dll (required by ...\WIFD1F~1\MpShHook.dll)"

We have one user with this problem running Vista. The other couple of users are running WinXP.

We don't use this dll at all so we are at a loss as to why our app (VFP 8/9) should complain. We have found that uninstalling Windows Defender and reinstalling it, or just installing it, or uninstalling Microsoft Spyware Removal Tool, or uninstalling Adobe 8 and reinstalling, solves the problem. I suspect that the uninstall / reinstall of an app which does use this dll correctly re-registers / installs the dll for apps that do need it.

Q1) Has anyone else seen this problem? If so what solutions did you come up with?

Q2) Why is VFP 8 and 9 complaining about a dll that it doesn't use?

NB: Not all our clients with MS Office 2007 are having this problem. It appears to affect just 3 or 4 users. Any other suggestions?
