How can I delete the old version of the controls and install the full version?
Search your hard drives for obout_*.dll and delete all.
Make sure you are searching on the correct machine.
Then add the licensed controls to your project.
If access is denied when you delete dll, do this:
1. Close InterDev and all other apps with references to dll.
2. Open IIS MMC. Open Properties for your web site.
3. Open tab 'Home Directory' and click button 'Unload'.
If it doesn't help, reboot PC and delete file.
On Windows 2003 click Start > Run > type IISReset.exe > Press OK > After reset replace dll.
On Windows 2003 go to IIS > Application Pools > Restart DefaultAppPool > Replace dll.
