Web Part Deployment in SharePoint

I've built a web part and after several deployments to a specific site, SharePoint suddenly won't give the option to deploy开发者_C百科 to a specifi site, a message is immediatelly displayed that the solution is deplyed globally.

I don't know what I did to cause this. I've been useing stsadmn -o addsolution method, except once when when I tried to just run the Setup.exe file.

Anyone has any idea why is it happenning and how to correct this.

Thanks,

EJM

First make sure to retract the solution (with stsadm), if it doesn't work, use -force/-override, and then delete with the same.

Than try to do it again, and it should work.
