plugin working most of the time

[programthat]

Hello,

I have created a plugin in the 1.1 framework (VS 2003) using the version 8 references.  The plugin creates a button on the toolbar.  For 90 percent of the computers I install it on it works fine.  For the other 10 percent the button does not show up.  How can I determine why the plugin does not create the button in the toolbar.  I read that if the plugin is in the dependentdlls.xml that means it was rejected.  Is this true, because it shows up in the list on machines that it works on as well. 

Thanks

After reading some further post on the forums I have determined that the issue was due to the fact that the machines not showing the toolbar button were not on the current version.  After the upgrade the plugin worked fine.
