I can tell you that Quickbooks is another such app. The fix, even for a multi-user version of Quickbooks, was to set certain registry keys to R/W for all users. If you can figure out, with regmon, if there are any keys that the application sets to Read only, when accessed by the first user, you may be able to use the same fix that we used for Quickbooks. - Good Luck -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Jeff Malczewski Sent: Tuesday, August 17, 2004 1:02 PM To: Thin Subject: [THIN] Only one instance?? I have an app that I'd like to run on TS but it only allows one instance of the application to run per machine. Does anyone know what causes this and how to get around it?? Any help would be greatly appreciated...
