• Possible conifguration problem... 2 hours ago Forums | ActiveState Community Site
  

  This is my first attempt to use TclApp. The application itself is a single file and (as far as I know) does not require any packages. When I run TclApp, I get the following message: (only the first part is shown)

  ====
  No known repository at D:/TclDevKit/tap_help_repository
  Local Installation? No: Repository "D:/TclDevKit/tap_help_repository": Does not exist
  Prefix file? No: Prefix "D:/TclDevKit/tap_help_repository": Does not exist
  ...
  ====

  It appears that the TclApp is using data from a previous installation. The TclDevKit is now installed at: C:\TclDevKit

  How can I correct this?

  Thanks
