Hi Michel,

>If I try with an administrator account, it works well. What else should I do to have a regular account to be able to execute the wc.dll file in such situation?

Does the regular account have read access to the WC.DLL, the VFP runtime, all scripts (if you use script mapping) and configuration files that WC uses? If you can't figure out which file you get an access denied message for, you can use FILEMON from http://www.sysinternals.com. It can log all error messages.
