Thanks for the reply Ed. I am not using the Setup Wizard provided by VFP. (using Setup Specialist). I have done installation in other sites without problems. My guess at this stage is the PC's OS or Server OS. For your info., the site is using Novell Server 4+ and Client 3.01. My colleague is at the site and he has tried to setup in another HP PC using Wins 95 and still the problem persist. I think this eliminates the PC's OS problem. I will ask him to try not logging in to eliminate problems from Novell.

The error is displayed immediately when he double-clicked the exe from the explorer. After this error, subsequent double-clicked will launch the app with no problem except exiting the app.

I have not apply the VS SP2 yet and will do this today.
Any advise??

Regards.

>The information you've provided has far from enough detail to make any sort of recommendation (or at least one that has a reasonable chance of fixing the problem.) In most cases, the first question to ask here is how was your application installed at the customer site? If it was not installed via a Setup Wizard generated installation, that'd be the first suspect. Simply copying files in place is not an adequate means of installing a VFP application.

>Next, look at the details of the customer's Win98 install. What patches have been applied (if any) through Windows Update? What other software (things like office, IE4 and the like) are there. IOW, make certain that the customer's installation is stable and up-to-date, and try comparing his system configuration to the one you have that's working fine.
