Thanks Alex Feldstein for help me...

I work with VF7 SP1 with Win2000 and i have OfficeXP installed.

Your cuestion:
- Why do you register with RUN /n .... from Click() ? You should register it only once,preferably not from your program but from the installation you create with a program like InstallShield or similar.

I code wrote in the event Click of button, for register it only once. I see example in fpress web: http://www.fpress.com/revista/Num0201/Truco.htm only for register the component OCX.

- Do you have MS Office installed in that computer?
Yes, i do.
In the computer with Windows 2003 Server its Office2003 Edition installed in the computer "server" its officeXP installed, maybe exists incompatibility of versions ?, my application this in a shared folder in Win2000 and other computers have a direct access to folder.

Sorry for my simple questions.
See u and thaks for you help.
